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.

A day after the U.S. Supreme Court denied Texas' challenge to Biden's 2020 presidential election victory, Trump supporters gathered in Washington, D.C. to protest alleged voter fraud.

The "March for Trump" event, which started at noon on Saturday, includes a march to the U.S. Supreme Court to "demand transparency and protect election integrity," according to promotional materials.

Former Trump administration national security adviser Mike Flynn was among those in attendance.

Trump tweeted Saturday morning that he just found out about the rally and said "I'll be seeing them."

On Friday, the Supreme Court rejected a lawsuit brought by the state of Texas and Republican allies of Trump to throw out millions of votes in four states and overturn Biden's victory. In dismissing the case, the court said Texas had no "cognizable interest" in how Pennsylvania, Michigan, Wisconsin and Georgia conduct their own elections.

The rally also comes as members of the Electoral College will meet Monday to formally cast their votes for president.
