Michigan state legislature closes offices due to 'credible threats of violence'

FDA Commissioner Stephen Hahn on Saturday pushed back on reports that he was threatened with firing.

Sources familiar with the matter told ABC News that in a Friday phone call, White House chief of staff Mark Meadows suggested to Hahn that his job could be on the line if his agency didn’t authorize emergency use of the Pfizer-BioNTech vaccine by the end of the day.

The Pfizer-BioNTech vaccine was authorized by the FDA late Friday.

“Representations in the press that I was threatened to be fired if we didn’t get it done by a certain date is inaccurate,” Hahn told reporters on a Saturday morning call.

Hahn said Saturday that the vaccine was authorized late Friday because science and data determined it was ready, not because of “any other external pressure” and that he would “absolutely” take the vaccine.

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.

The U.S. Supreme Court late Friday officially put to rest a brazen eleventh-hour attempt by the state of Texas and Republican allies of President Donald Trump to throw out millions of votes in four states and overturn Democrat Joe Biden’s victory in the 2020 presidential election.

In an unsigned, single-page order, the court rejected a lawsuit brought by Texas, citing a lack of standing under Article III of the Constitution. In dismissing the case, the court said Texas had no "cognizable interest" in how Pennsylvania, Michigan, Wisconsin and Georgia conduct their own elections.

The decision, coming just three days before the Electoral College meets to finalize the presidential selection, shut down what Trump had called "perhaps the most important case in history" without the justices getting into the merits of arguments on either side.

House Speaker Nancy Pelosi, D-Calif., excoriated the Supreme Court lawsuit from Texas seeking to overturn the presidential election results in key states, writing in a letter to colleagues on Friday that it is "an act of flailing GOP desperation" which "violates the principles enshrined in our American Democracy."

Quoting the Pennsylvania attorney general's brief calling it a "seditious abuse of the judicial process," she also accused  congressional Republicans who have supported the case of betraying their oaths of office and "subverting the Constitution."

The letter to colleagues comes after at least one Democratic member of the House called on Pelosi to refuse to seat incoming GOP representatives who signed onto the brief.
