I don’t know where you get that. Bowser claimed she turned down NG because she thought the police had it covered. The Capitol police chief requested NG and it was denied by the Sgt of Arms because of “optics”. Since the SoA workers directly for Pelosi either she gave the order or the SoA got a new frou frou vocabulary.
President Trump had no control over the Capitol. Remember the screaming that went on when he called in the NG when the WH was under seige? Pelosi was in charge, she either was in over her head or got the precise outcome she wanted.
It appears that you posted this comment 5 minutes after I posted a comment with a link to the Military Times, which you probably did not see. Suggest you read it now. It clarifies some of the details of who was doing what when. Bowser was already using NG for downtown traffic and Metro supervision. She need Pentagon permissions to use the DC NG on Capitol grounds. As soon as things were looking serious on local TV the Virginia gov. and subsequently the Maryland gov. offered their NG troops who also needed permission to go on Capitol grounds. Bowser made the DC Armory a staging area for the VA and MD NG once they had Pentagon permission to help at Capitol which apparently was not until near 6 pm when the curfew was to begin.
After reading the link below I don’t know where you get the idea that Polosi was in charge of the Capitol Police. Apparently on Jan. 4,the Chief of Capitol Police had asked the 3 person Capitol Police Board to declare an emergency and ask for NG support. The Board refused the request, and the House and Senate Sgts. at Arms have since resigned, although the Architect of the Capitol did not.
