Law enforcement officials were negotiating with a man who said he had a bomb in his pick-up truck near the U.S. Capitol on Thursday, causing nearby buildings to be evacuated as emergency vehicles rushed to the scene about a mile from the White House.

The U.S. Capitol Police said they did not know the man's motive but confirmed that he was livestreaming from the vehicle outside the Library of Congress, across the street from the Capitol.
