@bjorn0 said in FBI's Jill Sanborn: "I can't answer that.":
We know Trump was pleased with the attack by his own words, his lack of action, members of Trump's administration, those of aides to the VP, Kevin McCarthy leader of House Republicans on the floor of the House, and his aides reporting his call with the President which he did not deny, widely reported by the news segments of Fox News, even the opinion entertainment hosts were blaming him in private (now published) text messages to the White House.
You are making an assumption that you could never know if it is true. Using your same logic then Biden/Harris campaign and all the Democrats are responsible for the 30 deaths and billions of dollars of damage to federal buildings, police precincts and dozens of of minority owned small businesses during the 2020 riots. Where is that Congressional inquiry?
