Vehicle rams barricade outside Capitol

A U.S. Capitol Police officer has died after a driver crashed into a barricade on Constitution Avenue in Washington on Friday. Police shot and killed the driver, who exited his vehicle brandishing a knife and ran at two officers after crashing into them. The incident occurred near the Senate entrance to the Capitol. The building went on lockdown just after 1 p.m. Congress is in recess, and President Joe Biden left the White House earlier on Friday for Camp David.

Do we know what motivated the attack? Investigators are focusing on the mental health of the suspect, identified as 25-year-old Noah Green. In online posts that have since been removed, Green described being under government thought control and said he was being watched. He described himself as a follower of the Nation of Islam and its longtime leader, Louis Farrakhan. Police think the attack was an isolated incident and not terror-related.
