 Homeland Security Secretary John Kelly acknowledged Wednesday that President Donald Trump’s proposed wall on the southern border of the United States will not extend “from sea to shining sea” and could partially be fencing. 
  
 Kelly had few details about the size and scope of the wall when he testified in front of the Senate Homeland Security and Governmental Affairs Committee, saying the administration would rely on the input of those working on the border for the specifics. 
  
 "There is no way I can give the committee an estimate of how much it will cost," Kelly said. "I don’t know what it will be made of, I don’t know how high it will be, I don’t know if it’s going to have solar panels on its side and what the one side is going to look like and how’s it’s going to be painted." 
  
 "It’s unlikely that we will build a wall or physical barrier from sea to shining sea. But it is very likely, I’m committed, to putting it where the men and women say we should put it," he added. 
  
 A wall on the 2,000-mile border between the U.S.and Mexico was a signature campaign promise for Trump as part of his pledge to cut down on illegal immigration. He also declared that Mexico would pay for the barrier, despite consistent insistence by Mexican officials that they will never fund it. 
  
 The White House made a request for $1 billion to begin construction of the wall as part of its push to boost spending on defense and border security. But Democrats have vowed to block funding for the barrier and Republicans are wary of lumping the border request in with a broader spending bill to prevent a government shutdown before the April 28 deadline. 
  
 "The sooner we stop this, you know, we’re going to build a wall from sea to shining sea and the Mexicans are going to pay for it; it’s embarrassing," Democratic Sen. Claire McCaskill said Wednesday. "It’s not going to happen. Everybody in Congress knows it’s not going to happen." 
  
 The first round of bids for contractors hoping to construct the wall were due Tuesday. Senate Majority Leader Mitch McConnell estimated the full wall would cost between $12 to $15 billion, but a CNBC analysis found that number could rise up to $25 billion plus millions in annual maintenance. 
  
 In written testimony submitted to the committee, Kelly credited the president for a declining number of arrests of people caught trying to illegally cross the border. The head of Homeland Security said March was the fifth straight month border arrests declined and marked the lowest monthly number of arrests in the last 17 years. 
  
 "We’ve seen an absolutely amazing drop in the number of migrants coming out of Central America taking that terribly dangerous route from Central America into the United States," Kelly said. “It won’t last unless we do something, again, to secure the border. The wall, or physical barrier, something to secure our border.” 
  
 White House press secretary Sean Spicer said in a statement that the drop in arrests "demonstrates that the President's commitment to securing our border and supporting law enforcement is already showing results." ||||| This undated rendering provided by DarkPulse Technologies Inc. shows a proposed border wall between Mexico and the U.S. The wall proposed by Arizona-based DarkPulse Technologies would be constructed with...

 SAN DIEGO (AP) — Tuesday was the deadline for companies to propose designs for President Donald Trump's border wall with Mexico. U.S. Customs and Border Protection will ask several of the bidders to build prototypes in San Diego. 
  
 The government won't identify companies until contracts are awarded around June 1 — and even then, only the winners — but some bidders released plans on their own. 
  
 ___ 
  
 SOLAR PANELS 
  
 Gleason Partners LLC of Las Vegas proposes solar panels to cover sections of the wall. 
  
 The panels would provide electricity for lighting, sensors and patrol stations along the wall. Sales of electricity to utilities could cover the cost of construction in 20 years or less, according to the company. Power could also be sold to Mexico. 
  
 "I like the wall to be able to pay for itself," said managing partner Thomas Gleason. 
  
 ___ 
  
 TOURIST ATTRACTION 
  
 Crisis Resolution Security Services Inc. of Clarence, Illinois, proposes a wall that is 56 feet (17 meters) high and 22 feet (7 meters) wide at the top — with plenty of room to allow tourists to enjoy desert views. 
  
 The height — nearly twice what the government envisions — would deter climbers, and its width would give the structure longevity, said chief executive officer Michael Hari. 
  
 ___ 
  
 NUCLEAR WASTE 
  
 Clayton Industries Inc. of Pittsburgh proposes storing nuclear waste along the wall in trenches that are at least 100 feet (30 meters) deep. 
  
 Money already collected by the U.S. Department of Energy from people who benefit from nuclear power would help pay for the wall. 
  
 The bid includes an option for hardware to convert the nuclear waste to energy. 
  
 ___ 
  
 ARTWORK ON BOTH SIDES OF THE BORDER 
  
 Concrete Contractors Interstate of San Diego proposed a polished concrete wall augmented with stones and artifacts specific to areas on the 2,000-mile (3,218-kilometer) border. 
  
 Russ Baumgartner, CEO of the company, says the wall should be "a piece of art." 
  
 Customs and Border Protection's solicitation says the wall should be "aesthetically pleasing" from the U.S. side. Baumgartner wants to decorate both sides. 
  
 ___ 
  
 BALLISTIC CONCRETE 
  
 DarkPulse Technologies of Scottsdale, Arizona, proposes a concrete wall that can withstand tampering or attacks of any kind. 
  
 "You could fire a tank round at it and it will take the impact," said company founder Dennis O'Leary. 
  
 Fiber sensors would be embedded in the concrete to immediately alert officials to any attempts to climb over or tunnel under the wall. It would be coated with a slick coating that would prevent climbing. 
  
 ___ 
  
 NO BORDER 
  
 Otra Nation, a group of U.S. and Mexican citizens, proposed the world's first shared co-nation along the border "open to citizens of both countries and co-maintained by Mexico and the United States of America." 
  
 It would also create "nodes of cultural production" such as libraries, museums, galleries and workshops between San Diego and Tijuana, Mexico, and other spots with cities on both sides of the border. 
  
 It would prohibit oil drilling and mining and create a "hyperloop transportation system" for people and cargo. |||||
Output:
President Trump's vision of a "big, beautiful wall" along the entire length of America's border with Mexico probably won't become reality, Homeland Security chief John Kelly admitted during a Senate hearing Wednesday. Kelly told the Senate Homeland Security and Governmental Affairs Committee that he couldn't give them an estimate of how much the wall would cost, and it was unlikely that a physical barrier would be built "from sea to shining sea," NBC News reports. "I don't know what it will be made of, I don't know how high it will be, I don't know if it's going to have solar panels on its side and what the one side is going to look like and how's it's going to be painted," Kelly said. Kelly said he was committed, however, "to putting it where the men and women say we should put it." In response to a question from Sen. John McCain, Kelly said the "wall" Trump has been talking about could include electronic detection systems combined with patrols and fences in a system much like the existing one, the Los Angeles Times reports. Tuesday was the deadline for companies to propose border wall designs, the AP reports, and while the government won't identify bidders until contracts are awarded, those that publicly released proposals include Gleason Partners, which wants to include solar panels, and Clayton Industries, which proposes storing nuclear waste along the wall. (The White House has requested $1 billion for the first 62 miles of wall.)
