WASHINGTON, (Reuters) – The Pentagon announced Thursday that the Defense Secretary would approve all requests involving District of Columbia National Guard troops involved in civil law enforcement activities.

After a long-running Pentagon review, the Pentagon decided to make the move after reviewing how Washington D.C. handles National Guard requests.

With the power previously delegated by the defense secretary to the Army secretary, the district’s National Guard reports directly to the president.

This review took place after concerns were raised over whether or not the National Guard had been deployed in a timely manner to help prevent the attack on the U.S. Capitol.

According to a Pentagon statement, “The Secretary of Defense now has the sole approval authority for any requests that involve District of Columbia National Guard personnel directly participating in civil law enforcement activities or that requires the deployment of DCNG personnel (D.C. National Guard personnel) within 48 hours of receipt of the request.”

According to the Pentagon, a separate unit has been created within the building for these requests.

William Walker, then the District of Columbia’s National Guard commander, told senators during a hearing in March that Pentagon officials took more than three hours to approve a request by the U.S. Capitol Police for National Guard troops to back up police under attack by rioters at the Capitol on Jan. 6.

Supporters of Donald Trump led to the deaths of four persons and the death of one Capitol Police officer.

The hours-long assault left hundreds of officers injured and the Capitol was attacked by four more. Four other police officers were also hurt in the attack.
