Charles Flynn confirmed in a statement issued to The Washington Post on Wednesday that he was in the room for a tense Jan. 6 phone call during which the Capitol Police and D.C. officials pleaded with the Pentagon to dispatch the National Guard urgently, but top Army officials expressed concern about having the Guard at the Capitol.

Flynn left the room before the meeting was over, anticipating that then-Army Secretary Ryan McCarthy, who was in another meeting, would soon take action to deploy more guard members, he said.

“I entered the room after the call began and departed prior to the call ending as I believed a decision was imminent from the Secretary and I needed to be in my office to assist in executing the decision,” Flynn said…

The Army’s initial denial of Flynn’s participation in the critical Jan. 6 meeting, despite multiple inquiries on the matter, comes as lawmakers demand transparency from the Defense Department in the aftermath of one of Washington’s gravest national security failures, which left one police officer and four rioters dead, the Capitol desecrated and the lives of Vice President Mike Pence and members of Congress endangered.
