I see that some of the rioters were given tours of the capitol in days prior to the attack, and it sounds like they were given by republican congressmen.
"...lawmakers say that they witnessed an “an extremely high number of outside groups in the complex, on Jan. 5, which is unusual given that public tours of the Capitol ended in March 2020 due to the coronavirus pandemic." They also write that some of the visitors encountered by lawmakers “appeared to be associated” with the "Stop the Steal" rally that was held at the White House the next day, when Congress was certifying President-elect Joe Biden's victory in the Electoral College."
