If Pelosi called them and said put the National Guard around the Capitol Building you could be damn sure it would've happened. The people you cited answer to the Speaker of the House.No, Nancy Pelosi was not directly responsible for Capitol security on January 6, 2021. The security of the Capitol complex falls under the jurisdiction of the Capitol Police Board, which oversees the U.S. Capitol Police. This board consists of the House and Senate Sergeants at Arms, the Architect of the Capitol, and the Chief of the Capitol Police. While Pelosi, as Speaker of the House, did have influence, the operational decisions were primarily made by these security officials.
