They were ALL under house arrest during that greatest kayfabe ever on January 20, 2021. Don't make anon list out the hundreds of tells that it was a fake inauguration.
Anon will just go with the most obvious.
Bidan's "inauguration" was the FIRST Presidential Inauguration since 1953 where the "Presidential Salute Battery" from the 3d U.S. Infantry Regiment (The Old Guard), WAS NOT PRESENT to give the traditional 4-cannon, 21-gun salute, with The Old Guard located below the Capitol steps in "Presidential Park".
In fact, The Old Guard DID give President Trump its 4-cannon, 21-gun salute after he was inaugurated at Joint Airbase Andrews just before the Bidan Kayfabe. There is video of The Old Guard presenting the Salute at Andrews.
In trying to cover for the deafening silence which immediately followed Bidan's oath, fake news attempted to pass off the less precise, 3-cannon salute at Arlington Cemetery, after the Laying of the Wreath (Bidan was not allowed to touch The Wreath) ceremony at the Tomb of the Unknown Soldier, as the inaugural presidential salute.
Ask any Marine, or serious military, what's wrong with the attached photo, in addition to the masked Marine "yanking" guest Lady Gaga instead of offering her his arm.
