A gunman, identified as 31-year-old Cole Tomas Allen of Torrance, California, was arrested on the evening of April 25 after running through a security checkpoint at a hotel in Washington, D.C., where U.S. President Donald Trump, dozens of top officials in his administration and hundreds of members of the press were attending an annual event for White House reporters, Reuters reported. A Secret Service agent was shot but is expected to make a full recovery after the round hit his bulletproof vest. Cole's precise motivation remains unclear, but acting Attorney General Todd Blanche told reporters on April 26 that Cole was believed to have been targeting members of the Trump administration.
