From the technical standpoint of a transition of power, the public opinion of congressional Republicans about whether Biden will take office Jan. 20 matters almost not at all.

From the broader standpoint of democracy and faith in elections, it could not hardly matter more at this moment.

The process that so many Republicans have been saying they want to play out is rather thoroughly exhausted already. The next seven days bring significant deadlines, with Tuesday's congressional "safe harbor" deadline for state election results and next Monday's Electoral College voting the most significant.

His tweets and the 101 minutes Trump spent airing grievances and falsehoods in Georgia Saturday night made clear he will pursue his dangerous fictions right through the end of his presidency. The good of the Republican Party -- and, of course, the good of the country -- are, at best, secondary considerations for the president at this point.

Some Republicans are trying to reframe questions about Biden's legitimacy as president-elect as though they are merely asking questions. Their suggestion is that democracy is threatened if people believe election irregularities have been ignored.

But far from being brushed aside, Trump's claims have been rejected in courthouses and state houses -- including by Republicans who have found themselves targeted by the president.

Ignoring that fact only sows more doubt in election integrity and legitimacy. And continuing to give Trump space to make wildly inaccurate and irresponsible claims will only solidify his hold on a party whose best interests have already begun to diverge from the president's.

Before introducing more Cabinet nominees and administration picks to the public on Friday, Biden opened with a statement on Pfizer and BioNTech’s coronavirus vaccine, which the Food and Drug Administration is expected to approve for emergency use at any time.

"I want to make it clear to the public: You should have confidence in this. There is no political influence,” Biden said.

Biden’s remarks come as sources familiar with the matter tell ABC News White House chief of staff Mark Meadows in a phone call on Friday suggested to FDA Commissioner Dr. Stephen Hahn that his job could be on the line if his agency doesn't authorize the emergency use for the vaccine by the end of the day.
