It was in Washington Post- can’t get behind the paywall, so CNN will have to do.
Washington(CNN) The Army is now acknowledging that Lt. Gen. Charles Flynn, the brother of President Donald Trump's former national security adviser Michael Flynn, was in the room for one of the key January 6 phone calls in which DC government and US Capitol Police were asking for National Guard troops to quell the unfolding violence at the US Capitol.
The decision-making has come under scrutiny as city and Capitol Police officials have alleged that the Pentagon was slow to respond, while the Pentagon and Army maintain they never denied or delayed requests for the National Guard.
In official timelines released by the Department of Defense in the wake of the riot, Charles Flynn, the deputy chief of staff of the Army, was not listed as participating in any of the calls that day about mobilizing the National Guard to respond to the riot.
