evidence: "The Vice President has the power to reject fraudulently chosen electors," Trump declared falsely, lending credence to an erroneous theory that Pence can overturn the results of the election during Wednesday’s tally of Electoral College votes and again pressuring his top lieutenant to act outside constitutional bounds. [...] Pence and White House aides have tried to explain to the President that Pence’s role is more of a formality and he cannot unilaterally reject the Electoral College votes. Pence has walked Trump through his largely procedural role in hopes of downplaying the pressure on him, a strategy that doesn’t appear to have worked given the President explicitly urged him to take action Monday night without saying exactly what he wanted Pence to do. [...] On Sunday, Pence met for a lengthy session with the Senate Parliamentarian Elizabeth MacDonough in his office just off the Senate floor. Pence chief of staff Marc Short, who was also in the Capitol and seen at one point going into the office of Senate Majority Leader Mitch McConnell, denied the purpose of the meeting was to find a way to overturn the Electoral College results.
