Q: WASHINGTON (Reuters) - A U.S. Secret Service agent shot a man who brandished a gun near the White House on Friday while President Barack Obama was out golfing, and the man was taken to a hospital in critical condition, officials said. 
  
 The Secret Service, which protects the president and his family, briefly locked down the White House as a precaution, and Vice President Joe Biden was secured within the White House complex during the lockdown, a White House spokeswoman said. 
  
 Authorities later said there appeared to be no link to terrorism. 
  
 The shooting took place just off 17th and E streets, near what is known as the South Lawn outside the home and offices of the president. 
  
 A man carrying a gun approached a checkpoint shortly after 3 p.m. (1900 GMT) when uniformed Secret Service officers ordered him to stop and drop the weapon, the Secret Service said in a statement. 
  
 “When the subject failed to comply with the verbal commands, he was shot once by a Secret Service agent and taken into custody,” the statement said.The man was taken to hospital in critical condition, the District of Columbia Fire and Emergency Medical Services Department said. 
  
 Authorities said they were investigating the motive.

 “At this time, based on a preliminary investigation, there is no known nexus to terrorism,” security agencies said in a joint statement. 
  
 A man who appeared to be in his mid-20s walked to a gate of the White House holding a silver-colored gun pointed at the ground, said Brett Polivka, a 26-year-old visitor from Texas who was near the south side of the White House. 
  
 “A couple officers drew their guns, went right at him and within two or three seconds we heard a gunshot,” Polivka said. 
  
 The Secret Service, which also guards other top dignitaries, said all those under its protection were safe, but it did not say if Obama’s family was home at the time. 
  
 “Everyone in the White House is safe and accounted for,” a White House official said. 
  
 The shooting followed several incidents that raised questions about the Secret Service’s performance. 
  
 In September 2014, a knife-carrying man jumped a fence and ran into the White House itself in one of the worst security breaches during Obama’s tenure.

 That episode led to the resignation of the Secret Service’s director. 
  
 In March 2015, two Secret Service agents capped off a night of drinking by driving into a White House barricade inches away from a suspicious package that investigators were examining. 
  
 In 2011, a man hit the White House with automatic rifle fire, though damage to the building was not discovered for several days. ||||| The man shot by a U.S. Secret Service officer near the White House Friday remains in critical condition in a Washington hospital, a hospital spokeswoman said Saturday. 
  
 George Washington University Hospital spokeswoman Susan Griffiths would provide only his condition, according to The Associated Press. She referred other questions to the Secret Service, but a spokesman for that agency, Robert Hoback, declined to discuss the case, citing the continuing investigation. 
  
 The White House was locked down for around 45 minutes Friday afternoon after a man -- identified by ABC sources as Pennsylvania resident Jesse A. Olivieri -- carrying a gun near the complex was shot by a Secret Service agent 
  
 Just after 3 p.m., Olivieri, who was carrying a gun, approached a Secret Service checkpoint on the outer perimeter of the White House grounds, near 17th and E Street Northwest. 
  
 He ignored commands from Secret Service officers to drop his weapon, and began brandishing his firearm, the official said. 
  
 A Secret Service agent then fired a single shot at Olivieri, wounding him, according to the official. He was then taken into custody and Secret Service personnel administered first aid. 
  
 Olivieri was transported to a local hospital, where he is being treated. 
  
 The president was not in the White House at the time of the incident and the lockdown was lifted just after 4 p.m. Vice President Biden was reported to be “within the complex” at the White House, but is “secure," according to a spokesperson.
