To believe that Pelosi had "nothing to do" with the two refusals of the requests to use National Guard (NG) troops to help guard the Capitol on January 6, you would have to assume that the House Sergeant at Arms twice rejected those requests without bothering to consult with Pelosi, a very unlikely scenario.
January 6 was the day the Senate would certify the Electoral College results. The whole world knew that a massive protest was going to occur and that tensions were sky high. It boggles the mind to suggest that the House Sergeant at Arms would make such an enormous decision on security without consulting with his boss, Pelosi. I find such a scenario incredibly hard to believe.
Remember that it was Pelosi who ordered NG troops to guard the Capitol *after* January 6. She kept them there for five months, long after there was any credible reason for making them stay there. Yet, we are supposed to believe that she had nothing to do with the rejections of the requests to use NG troops to help guard the Capitol on January 6.
And what about the documented evidence that one of Schumer's top aides received credible, specific FBI intel that some of the protestors would storm the Capitol? Here, too, it boggles the mind to believe that the aide did not immediately discuss this intel with Schumer. Yet, neither Schumer nor the aide shared that intel with the Capitol police, nor did they act on that intel. Schumer surely was advised of the intel, and his failure to act clearly suggests that he wanted the riot to occur because he knew the Democrats could use it as a propaganda weapon against Trump and the Republicans.
As a deep purple Independent, I'm perfectly willing to acknowledge that Trump committed a crime when he refused to immediately call on his supporters to stand down and go home after the riot began. But I'm also willing to admit that Pelosi and Schumer clearly seemed to want the riot to occur, given Schumer's failure to act on the FBI intel and given Pelosi's apparent refusal to allow NG troops to be used to help guard the Capitol.
