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.

Biden is introducing more nominees and picks for the incoming administration from Wilmington, Delaware, and while the resurgence of Obama-era officials has some Democrats worried the president-elect is relying so heavily on his longtime allies, Biden argued the choice behind each of his picks Friday.

"Vice President-Elect Harris and I knew we’d have our work cut out for us when we got elected, but we also knew we could build a team that would meet this unique and challenging moment in American history. Some are familiar faces. Some are new in their roles," Biden said. "Above all, they know how government should and can work for all Americans."

For secretary of agriculture, Biden’s nominating Tom Vilsack, who served in the same post throughout the Obama administration. Vilsack previously served two-terms as governor of Iowa.

For secretary of Housing and Urban Development, Biden chose Rep. Marcia Fudge, who has represented Ohio's 11th Congressional District for the last 12 years. If confirmed, she will be the first woman to lead the department in more than four decades.

For secretary of veterans affairs, Biden is nominating former President Barack Obama’s former chief of staff, Denis McDonough. McDonough also served as deputy national security adviser and chief of staff of the National Security Council during the Obama administration.

Biden picked Katherine Tai for U.S. trade representative. Tai currently serves as the chief lawyer on trade for the Ways and Means Committee in the House of Representatives and previously was chief counsel for China trade enforcement in the office of the U.S. trade representative.

For director of the White House Domestic Policy Council, Biden has appointed Susan Rice. Rice served as U.S. ambassador to the United Nations and later as national security adviser in the Obama administration.
