The officer who fatally shot Ashli Babbitt inside the U.S. Capitol on Jan. 6 will not face disciplinary action. The announcement comes after an internal U.S. Capitol Police administrative investigation into the incident.

Babbitt, a 35-year-old Air Force veteran, was seen on video with other insurrectionists smashing the glass on the doors leading to the Speaker’s Lobby in the Capitol. The incident was captured on video that day and reported by the Washington Post and other outlets. While attempting to climb through the broken glass of the doors, Babbitt was shot by an officer on the other side.

The officer involved in the shooting is not being identified. USCP’s Office of Professional Responsibility said in a press released Monday that the officer’s actions were lawful and within department policy.

“An officer may use deadly force only when the officer reasonably believes that action is in the defense of human life, including the officer’s own life, or in the defense of any person in the immediate danger of serious physical injury,” the release read.

The officer and his family “have been subject to numerous credible and specific threats for actions that were taken as part of the job of all our officers: defending the Congress, members and the democratic process,” read the release.

In April, U.S. Attorney’s Office for the District of Columbia announced they would not pursue criminal charges against the officer, stating that there was insufficient evidence to do so.

“The investigation revealed no evidence to establish that, at the time the officer fired a single shot at Ms. Babbitt, the officer did not reasonably believe that it was necessary to do so in self-defense or in defense of the Members of Congress and others evacuating the House Chamber,” a press release from the U.S. Attorney’s Office read.

Babbitt was one of five people, including Capitol Police Officer Brian Sicknick, who died in or around the riot. During the insurrection on Jan. 6, more than 50 officers from Capitol Police and D.C. Police were injured, according to former Capitol Police Chief Steven Sund. At least two officers died by suicide following the events on Jan. 6 and others reported psychological trauma.

A correction was made to this story reflecting that Ashli Babbitt was 35 years old when she died.
