However, on the eve of Robert Mueller's appointment as a special counsel to investigate allegations of collusion between Russian officials and the Trump 2016 campaign, Pelosi tweeted: "Our election was hijacked. There is no question. Congress has a duty to #ProtectOurDemocracy & #FollowTheFacts."
Pence uses Pelosi's own words to justify not invoking the 25th Amendment
Vice President Mike Pence told Speaker of the House Nancy Pelosi that he will not invoke the 25th Amendment, as lawmakers flooded into the House chamber for a vote Tuesday night on a resolution calling for him to do so.
"Last week, I did not yield to pressure to exert power beyond my constitutional authority to determine the outcome of the election," Pence said to the speaker in an evening letter. "And I will not now yield to efforts in the House of Representatives to play political games at a time so serious in the life of our nation."
"Just a few months ago, when you introduced legislation to create a 25th Amendment Commission, you said, [a] President’s fitness for office must be determined by science and facts'," Pence wrote. "You said that we must be very respectful of not making a judgment on the basis of a comment or behavior that we don’t like, but based on a medical decision.
"Madam Speaker you were right," the vice president added.
