Capitol Police have evacuated the Cannon House Office Building, the Library of Congress's Jefferson Building and other buildings nearby as they investigate an "active bomb threat" near the Capitol building.
Streets have been blocked off as police negotiate with a suspect in a black pickup truck that was driven “onto the sidewalk in front of the Library of Congress” around 9:15 a.m.
“The driver of the truck told the responding officer on the scene that he had a bomb and what the officer said appeared to be a detonator in the man's hand,” Capitol Police Chief Thomas Manger said during a brief press conference.
Manger said the department immediately evacuated the nearby buildings as a result. Though the House and Senate are currently in recess, Manger noted “there's still people working throughout some of the buildings that were nearby this location.”
A spokesperson for the Supreme Court, which remains closed to the public due to the coronavirus pandemic, said the court building was also evacuated shortly after 10 a.m.
The suspect is male, but police have not released the man's identity or discussed a motive.
"We don't know a whole lot. We do have a possible name, an identity of the suspect, but we don't have much information at all about him at this time. We're going to give periodic updates," Manger said.
He added that negotiations with the man remain ongoing.
“My negotiators are hard at work trying to have a peaceful resolution to this incident,” he said.
A law enforcement official told CNN that the suspect had posted video on social media. Multiple outlets including CNN and Reuters reported that a man was seen in video talking about "revolution" while appearing to hold a metal canister.
A spokesman for Facebook confirmed that the company had deactivated a livestream and removed the individual's profile as it investigates.
The incident is just the latest tense moment on Capitol Hill following the Jan. 6 attack on the Capitol building by a mob of former President TrumpDonald TrumpSenate rejects attempt to block Biden's Saudi arms sale Crenshaw slams House Freedom Caucus members as 'grifters,' 'performance artists' Senate confirms Biden's nominee to lead Customs and Border Protection MORE's supporters. Four Capitol Police officers have died by suicide — deaths that have been linked to the attack — and another officer died the day after the attack.
In May, another Capitol Police officer was killed when a man rammed his car into a barricade outside the building. The man who drove that car was shot and killed after he left his vehicle and lunged at an officer with a knife.
