Police identify officer slain in vehicle attack on Capitol as 18-year veteran William Evans

• The other officer who was struck by the car is stable, according to U.S. Capitol Police.
• House Speaker Nancy Pelosi (D-Calif.) has ordered Capitol flags to half-staff in honor of Evans. President Biden also ordered the White House flags to be flown at half-staff.
• A lockdown at the Capitol has been lifted, but the area surrounding the incident will continue to be restricted.

Biden on Friday said in a statement: "[Dr. Biden] and I were heartbroken to learn of the violent attack at a security checkpoint on the U.S. Capitol grounds, which killed Officer William Evans of the U.S. Capitol Police, and left a fellow officer fighting for his life..."

• "I have been receiving ongoing briefings from my Homeland Security Advisor, and will be getting further updates as the investigation proceeds," the president added.

The big picture: Some security fencing was removed a week ago after heightened security following the Jan 6. attack. National Guard members remain at the U.S. Capitol but in smaller numbers. Members of the Guard were seen on Friday deploying toward the Capitol barrier following the incident.

• As law enforcement responded to the attack, Capitol staff received a text alert from Capitol Police warning them stay away from exterior doors and windows in the Capitol and to "seek cover" if outdoors.

Of note: Biden is away from D.C. and visiting Camp David. The House and Senate are out of session.
