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 headed to Philadelphia today for a follow-up foot scan, two weeks after sustaining small hairline fractures in his mid-foot.

“The president-elect will have a follow-up appointment at the radiology department of the Pennsylvania Hospital,” according to the Office of President-elect Biden.

Biden’s doctor, Dr. Kevin O’Connor, provided more background on the scan in a statement.

“Consistent with our original plan, President-elect Biden will receive routine 2-week post-injury imaging today. This will be performed with a special CT scanner which is able to obtain a “weight-bearing” image. Now that the initial discomfort and swelling are decreased, it is important to observe the structures within the midfoot under the actual pressure of standing. This is the best way to assure ankle and foot stability,” the statement said.

After the scan, O’Connor said: “Weight-bearing CT results were very encouraging. The small fracture in the intermediate cuneiform is barely detectable and the small fracture in the lateral cuneiform is healing as expected. No more extensive injury was identified.”

Biden was spotted as he was leaving the appointment, where he waved and gave a thumbs up to the press corps.

There was a group of people gathered who cheered for Biden. Biden clearly noticed that one man was not wearing a mask and signaled as if to suggest he put one on. The older man just began to blow kisses as the president-elect, according to the TV pooler.

Biden then headed back to Wilmington.
