Acting Attorney General Todd Blanche said that he believes the suspected gunman at the White House Correspondents' Association dinner was targeting administration officials, noting "we're still looking into" whether President Donald Trump was specifically targeted.

Blanche stressed that the investigation was "quite preliminary" and said that law enforcement was investigating further information about the suspect, including "some writings," and speaking with people who knew him. The suspect is not cooperating with investigators, he added.
