The driver that rammed their auto into two US Capitol police officers and a barricade has also died after being shot by police.
The incident comes as the security situation on Capitol Hill remains top of mind for many lawmakers despite a recent ramping down of some additional protective measures that were put into place after the January 6 insurrection. The suspect was shot and died at the hospital. The email stated Capitol Police officers shot the suspect after he rammed the barricade and exited holding a knife.
"The DC National Guard deployed a Immediate Response Force (IRF) composed of National Guard soldiers and airmen to the Capitol complex this afternoon to support the U.S. Capitol Police". It comes as the Washington region remains on edge almost three months after a mob of armed insurrectionists stormed the Capitol as Congress was voting to certify Joe Biden's presidential win.
No entry or exit is being permitted, and police said: "If you are outside, seek cover". But the attack underscores that the building and campus - and the officers charged with protecting them - remain potential targets for violence. "A suspect is in custody".

"We do not have the suspect on file with U.S. Capitol Police", Acting Metro Police Department Chief Robert Contee said. All three people involved, the two officers and the driver, were taken to the hospital.
The incident occurred as both the House and Senate were in recess, though both buildings have staff - and reporters - working inside.
The U.S. Capitol was placed under lockdown amid what Capitol Police described as "an external security threat". Fencing that prevented vehicular traffic near that area was recently removed.
Video from reporters at the scene posted on Twitter appeared to show a vehicle that had crashed into a barrier. Law enforcement and paramedics could be seen caring for at least one unidentified individual.
President Joe Biden had just departed the White House for Camp David when the attack occurred. As customary, he was travelling with a member of the National Security Council Staff who was expected to brief him on the incident.
