The Capitol Police officer who fatally shot Air Force veteran Ashli Babbitt on Jan. 6 as she joined a pro-Trump mob ransacking the Capitol will not face criminal charges, the Justice Department said on Wednesday.

Driving the news: In their investigation, federal prosecutors determined that there was "insufficient evidence to support a criminal prosecution."

• The officer who fired the shot that killed Babbit was placed on administrative leave within days of the Capitol attack.

Details: Babbitt was shot in the left shoulder by an officer after she tried to climb through a broken window on a door into the Speaker's Lobby — located just off the House chamber floor.

• A USCP response team administered aid to Babbit before she was transported to Washington Hospital Center, where she died from her injuries.
