President Obama interrupted his O'ahu vacation today to make his first statement about the attempted Christmas Day bombing of a Northwest Airline flight and to rush off the golf course when the son of one of his friends suffered a slight injury on the beach in Kailua. 
 
 "The first family is fine," said Bill Burton, deputy White House press secretary. "... Eric and Cheryl Whitaker's son was examined and released from the hospital. He is home playing with his friends and just fine." 
 
 Obama had gone to Luana Hills Country Club around 10:40 a.m. following a game of tennis at the Kailua Racquet Club with the first lady — and after his statement at Marine Corps Base Hawaii. 
 
 At the golf course, according to Darren Sumimoto, the club's general manager, "All of a sudden they just came and left. We didn't see anything." 
 
 An administration official told pool reporters that the boy suffered a "run-of-the-mill beach injury" that initially was thought to need stitches. Obama left the golf course immediately to make sure the boy was with his parents and returned to his vacation home "in a very high speed and dramatic motorcade," according to a media pool report. 
 
 After it was determined that the injury was minor, the president returned to the golf course, where he golfed until sundown and did not get a full 18 holes in. The golfing party consisted of several groups and included, among others, Marty Nesbitt, Reggie Love and Ben Finkenbinder. 
 
 Obama was back at the Kailua house at 6 p.m. 
 
 Sources told The Advertiser that the child was treated at the vacation compound and was not transported to The Queen's Medical Center, although Secret Service agents were stationed at Queen's. At least six Secret Service agents and five security guards from Queen's kept media at a distance from Hawaii's major trauma center. 
 
 Obama's fifth day of his annual O'ahu Christmas vacation began with his usual early morning workout at Marine Corps Base Hawai'i's "Semper Fit" gym, followed by a tennis workout with his wife that was barred to the media. 
 
 The president then made his first public remarks since arriving in Hawai'i during a 7-minute press conference at the Marine Corps base's Kane'ohe Klipper Golf Course clubhouse at 10:03 a.m. 
 
 Obama discussed the bombing attempt of the Detroit-bound jet and the government crackdown of protestors in Iran at the Marine Corps Base Hawai'i clubhouse meeting room. 
 
 Before Obama spoke, an aide carefully affixed the presidential seal to a podium backed by the U.S. and presidential flags and temporarily-erected deep blue drapes. 
 
 The motorcade pulled up at 9:59 a.m. and Obama said, "Hey guys. Good morning everybody." 
 
 Wearing a Navy suit and white shirt without a tie, Obama spoke of the steps taken following the bombing attempt. 
 
 Obama also condemned government opposition to protestors in Iran that resulted in at least 15 deaths. 
 
 "The United States joins with the international community in strongly condemning the violent and unjust suppression of innocent Iranian citizens, which has apparently resulted in detentions, injuries and even death," he said. 
 
 Obama, who was accompanied by at least six unidentified people who were not part of his staff, did not take any questions. 
 
 For increasing numbers of Marines at Kane'ohe Bay, Obama's workouts and appearances on base have provided a brush with both the president of the United States and their commander in chief. 
 
 Pfc. Jeffrey Scarmazzi, 22, from Jessup, Md., videotaped Obama's appearance for the base's "combat camera" unit. It was Scarmazzi's first presidential press conference. 
 
 "It was nice being on the inside," Scarmazzi said. The setup for the press conference "ran smooth until they let the press pool in — photographers were springing and hopping all over the place." 
 
 Scarmazzi was taken with Obama's initial greeting to the press. 
 
 "Kind of unexpected informality on his part," Scarmazzi said. 
 
 Lance Cpl. Colby Brown, 20, from Redmond, Ore., got to meet the president in the Anderson Hall chow hall on Christmas Day. 
 
 "I shook his hand," Brown said. "He asked me how I was doing and then he asked me if I was having a good Christmas, and if I had called my Mom and Dad." 
 
 Brown said Obama greeted everyone seated at the chow hall on Christmas — at least 75 Marines, sailors, soldiers and family members. 
 
 "I think it's pretty cool," Brown said. "It's not every day you get to meet your commander in chief. He seemed pretty nice. Seemed like he actually cared." ||||| President Obama was unexpectedly taken away from a golf course in Hawaii on Monday and returned to the beachfront compound where he has been staying because the son of one of his friends had been hurt. 
 
 A White House spokesman, Bill Burton, said that the president and his family were unhurt. 
 
 An official said the person whose son was injured was Dr. Eric Whitaker, who along with other friends of Mr. Obama has been staying in a three-house compound rented in the Kailua area outside Honolulu. 
 
 Mr. Obama, Dr. Whitaker and others had been golfing at the Luana Hills Country Club for about an hour when they suddenly jumped into the presidential motorcade and made a dramatic, high-speed departure. The unexpected move triggered concerns about whether the president was injured, particularly after an ambulance with flashing lights sped to the compound. The White House at first did not explain the incident out of concern for the privacy of the Whitakers, but later sent Mr. Burton to tell reporters the first family was uninjured. 
 
 The ambulance left after about 15 minutes at the compound, followed by a black sedan. Mr. Obama returned via motorcade to the golf course. An administration official said no stitches were needed. ||||| On Friday, President Trump and his entourage will jet for the third straight weekend to a working getaway at his oceanfront Mar-a-Lago Club in Palm Beach, Fla. 
 
 On Saturday, Trump’s sons Eric and Don Jr., with their Secret Service details in tow, will be nearly 8,000 miles away in the United Arab Emirates, attending the grand opening of a Trump-brand golf resort in the “Beverly Hills of Dubai.” 
 
 Meanwhile, New York police will keep watch outside Trump Tower in Manhattan, the chosen home of first lady Melania Trump and son Barron. And the tiny township of Bedminster, N.J., is preparing for the daunting prospect that the local Trump golf course will serve as a sort of northern White House for as many as 10 weekends a year. 
 
 Barely a month into the Trump presidency, the unusually elaborate lifestyle of America’s new first family is straining the Secret Service and security officials, stirring financial and logistical concerns in several local communities, and costing far beyond what has been typical for past presidents — a price tag that, based on past assessments of presidential travel and security costs, could balloon into the hundreds of millions of dollars over the course of a four-year term. 
 
 Adding to the costs and complications is Trump’s inclination to conduct official business surrounded by crowds of people, such as his decision last weekend to host Japanese Prime Minister Shinzo Abe for a working dinner while Mar-a-Lago members dined nearby.

 The handful of government agencies that bear the brunt of the expenses, including the Defense and Homeland Security departments, have not responded to Washington Post requests for data laying out the costs since Trump took office. 
 
 But some figures have dribbled out, while others can be gleaned from government documents. 
 
 Trump’s three Mar-a-Lago trips since the inauguration have probably cost the federal treasury about $10 million, based on figures used in an October government report analyzing White House travel, including money for Coast Guard units to patrol the exposed shoreline and other military, security and staffing expenses associated with moving the apparatus of the presidency. 
 
 Palm Beach County officials plan to ask Washington to reimburse tens of thousands of dollars a day in expenses for deputies handling added security and traffic issues around the cramped Florida island whenever Trump is in town. 
 
 In New York, the city is paying $500,000 a day to guard Trump Tower, according to police officials’ estimates, an amount that could reach $183 million a year. 
 
 This month, The Post reported that Secret Service and U.S. Embassy staffers paid nearly $100,000 in hotel-room bills to support Eric Trump’s trip to promote a Trump-brand condo tower in Uruguay. 
 
 “This is an expensive way to conduct business, and the president should recognize that,” said Tom Fitton, president of the conservative group Judicial Watch, which closely tracked President Barack Obama’s family vacation costs and said that it intends to continue the effort for the Trump administration.

 “The unique thing about President Trump is that he knows what it costs to run a plane,” Fitton added, noting that Trump should consider using the presidential retreat of Camp David, a short helicopter ride from the White House, or even his golf course in Northern Virginia. Of Mar-a-Lago, Fitton said, “Going down there ain’t free.” 
 
 For Trump, the costs come with an additional perk: Some of the money flows into his own pocket. While Trump has removed himself from managing his company, he has refused to divest his ownership, meaning that he benefits from corporate successes such as government contracts. 
 
 [Documents confirm Trump still benefiting from his business] 
 
 The Defense Department and Secret Service, for instance, have sought to rent space in Trump Tower, where leasing a floor can cost $1.5 million a year — though neither agency has disclosed any details. In addition, Trump’s travel to his signature properties while trailed by a press corps beaming images to the world allows the official business of the presidency to double as marketing opportunities for his brand. 
 
 The White House did not address broader concerns of the costs and potential conflicts inherent in Trump’s early travels. But White House spokeswoman Stephanie Grisham told The Post this week that Trump is always working, even when he has left Washington behind. 
 
 “He is not vacationing when he goes to Mar-a-Lago,” Grisham said. “The president works nonstop every day of the week, no matter where he is.” 
 
 Trump’s frequent travel belies his repeated criticism of Obama as a “habitual vacationer” enjoying taxpayer-funded golf getaways. It also comes after his own promises: He told the Hill newspaper in 2015, “I would rarely leave the White House because there’s so much work to be done.” 
 
 Presidential families have for decades been guaranteed round-the-clock protection, no matter the expense or destination. Every presidency has brought new operational challenges and lifestyle habits, from George W. Bush’s frequent stays at his remote ranch in Texas to Obama’s annual trips to Martha’s Vineyard and his native state of Hawaii. Judicial Watch estimated that Obama-related travel expenses totaled nearly $97 million over eight years. 
 
 But based on the first four weeks, Trump’s presidency appears on track to cost hundreds of millions of dollars more. 
 
 [Can he do that? How Trump is changing the American presidency] 
 
 The burden is especially acute for the Secret Service, the presidential protection force that has endured years of budget short­ages, low morale and leadership shake-ups, including the announcement this week that its director, Joseph Clancy, is stepping down. 
 
 Agents are now tasked with guarding multiple homes and protecting Trump’s four adult children, including the globe-trotting sons running the family business and daughter Ivanka, whose family recently moved into a Northwest Washington neighborhood. 
 
 “There was an anticipation of how stressful it was going to be on the agency, but the harsh reality is that the stress is just overwhelming,” said Jonathan Wackrow, a 14-year Secret Service employee who served in Obama’s detail and now works as executive director of the risk-mitigation company RANE. 
 
 Even veteran agents, Wackrow said, are feeling the pressure of the “monumental” task, including manning high-security perimeters in Washington, Florida and New York, along with protecting family members’ private-business travel across three continents. 
 
 “It’s a logistical nightmare,” Wackrow said. Agents are “at severe risk of burnout, and the very last thing you want is to have your agents burned out.” 
 
 A Secret Service spokesman said the agency is equipped to handle the demands of a Trump presidency. “Every administration presents unique challenges to which the Secret Service has effectively adapted,” according to an agency statement. “Regardless of location . . . the Secret Service is confident in our security plan.” 
 
 Experts and local officials have pointed to security and logistical concerns surrounding Mar-a-Lago, the lavish estate that Trump turned into a club in 1995 and now calls the “Winter White House.”

 Club members pay $200,000 to join — a fee that has doubled since his election — and $14,000 a year to belong, giving them access to the beach, tennis courts, a spa and, now, on occasional weekends, to the president. 
 
 But Rep. Lois Frankel (D-Fla.), who represents Palm Beach, said Mar-a-Lago is a poor choice for a president’s long-term home: an exposed oceanfront club on a narrow, busy island, where traffic problems were already routine. 
 
 “Mar-a-Lago is no Camp David,” Frankel said. “It’s not set up with the intention or the forethought of keeping the president safe.” 
 
 The challenges for Mar-a-Lago as a presidential home were apparent from pictures posted on social media last weekend by club guests — including close-up images of the presidential limousine and a picture of a military official carrying the nuclear “football.” 
 
 In one Instagram video recorded Friday night outside Mar-a-Lago, a woman fawns as men with earpieces inspect under the hood of a line of cars heading into the club: “The Secret Service is so hot.” 
 
 The weekend brought the presidential entourage to two other Trump properties, as Trump and Abe golfed 27 holes at the president’s courses in Jupiter and West Palm Beach. The events meant global publicity for the Trump brand — and even more security complications. 
 
 The federal and local governments have spent considerable sums to help safeguard the sprawling estate on items big and small. 
 
 In advance of Trump’s Super Bowl weekend trip to Mar-a-Lago, the Secret Service paid for a bevy of security costs, including more than $12,000 for tents, portable toilets, light towers and golf carts, purchase orders show. 
 
 The bills have racked up outside the club, too. Palm Beach County Sheriff Ric Bradshaw said Trump’s 25 days in the county since the election have cost local taxpayers about $60,000 a day in overtime police payments. 
 
 Local officials said the U.S. Coast Guard has run round-the-clock shoreline patrols alongside Mar-a-Lago when the president is in town. A Coast Guard spokesman declined to share costs or specifics, citing security concerns. 
 
 The Town of Palm Beach recently implemented a “presidential visit seasonal traffic mitigation plan” in hopes of stemming the island’s worsening traffic woes. Running every weekend until May, the plan includes a town order demanding sanitation and public-works crews leave the island every Friday by 3 p.m. 
 
 Local officials usually learn only a few days in advance that the president is coming, said Kirk ­Blouin, the town’s director of public safety. “We plan as if he is going to be here most weekends,” Blouin said, “because otherwise it’s too hard to plan.” 
 
 Overseas travel by Trump’s adult sons is adding to the burden on taxpayers. 
 
 Eric Trump and his security detail flew this month to the Dominican Republic, during which the president’s son met with developers proposing a Trump-brand luxury resort. Purchase orders showing government expenditures for that trip are not yet available, but records show that Secret Service officials traveled there in advance to scope out the area — staying at the five-star, oceanfront AlSol Del Mar hotel at a cost of $5,470. 
 
 After this weekend’s trip to Dubai — during which early Secret Service hotel bills have already surpassed $16,000, records show — the Trump brothers will travel to Vancouver, B.C., for the Feb. 28 grand opening of another Trump-brand skyscraper.

 The State Department has declined to provide details related to its expenditures for Trump family travel around the world, including the participation of embassy staffers when Eric Trump and Don Trump Jr. travel on behalf of the family business. 
 
 The best public estimate for the full cost of Trump’s presidential getaways may come from a U.S. Government Accountability Office report in October, which estimated that a four-day trip for President Obama cost taxpayers more than $3.6 million. 
 
 During that Presidents’ Day weekend trip in 2013, Obama flew to Chicago to give an economic speech, then to Palm City, Fla., to golf with Tiger Woods and the owner of the Houston Astros baseball team. 
 
 That money went toward operating aircraft flown in from 10 states — including Air Force One, which costs an estimated $200,000 an hour to fly — as well as assorted watercraft, military working dogs, rental cars, hotel rooms and a Coast Guard rescue helicopter. 
 
 The trip drew the ire of many Republicans in Congress, including Sen. John Barrasso (R-Wyo.), who requested that the GAO review Obama’s costs. Asked whether Barrasso would file a similar request for Trump’s trips, his spokeswoman said equating the two presidents’ trips would be “misleading at best.” 
 
 “Former President Obama flew to Florida for the express purpose of a golf lesson and a round of golf with Tiger Woods. President Trump was in Florida with the Prime Minister of Japan,” Barrasso’s press secretary, Laura M. Mengelkamp, said in a statement. “Regardless, every level of the federal government needs to be mindful of the way it spends taxpayer dollars.” 
 
 In November, when Trump spent a weekend at his Trump National Golf Club in Bedminster, N.J., the 8,000-resident township received just 48 hours’ notice demanding an all-hours security detail of six police officers from its 16-officer force. 
 
 Township officials have begun preparing for the possibility that Trump will make up to 10 visits this year, including a potentially extended summer stay for the first lady. Officials there offered a projection, based on seven Trump trips, that could cost the township more than $300,000. 
 
 “Bedminster is a small municipality with a small police force and a small budget,” Mayor Steven E. Parker (R) wrote in a letter asking for federal help in recouping security costs. “We want to welcome President Trump with open arms, but we don’t wish to burden our taxpayers disproportionately for these visits.”

– President Obama interrupted a round of golf this afternoon, raising concerns because an ambulance was seen at the home where he is vacationing, but all is well with the first family, the Honolulu Advertiser reports. A child vacationing with the Obamas suffered a "run-of-the-mill beach injury," according to a White House spokesman who declined to name the boy. He is a son of Eric Whitaker, who was golfing with the president, the New York Times reports. A motorcade sped away from the Luana Hills Country Club, where Obama had gone to play after speaking about Friday's attempted bombing of Northwest Flight 253, and reporters were told the situation involved neither national security nor Obama's safety. "Nobody saw him playing," said the country club's GM. "All of a sudden they just came and left." The president later returned to the course.
