• Federal prosecutors want former Trump White House aide Steve Bannon to begin serving his four-month jail sentence for criminal contempt of Congress.
• Prosecutors cited Bannon's recent loss of an appeal of his conviction.
• Bannon refused to comply with subpoenas seeking his testimony and documents from a House committee investigating the Jan. 6, 2021, riot at the U.S. Capitol.
• Bannon had been free pending his appeal after a judge ruled that his bid to overturn his conviction was likely to succeed.

Federal prosecutors on Tuesday asked a judge to order former Trump White House aide Steven Bannon to begin serving his four-month jail sentence for contempt of Congress, citing a recent appeals court decision upholding his conviction.

If the motion is granted, Bannon soon could be required to report to jail and serve his sentence for refusing to comply with subpoenas from a House committee investigating the Jan. 6, 2021, attack on the U.S. Capitol.

"The United States of America requests that the Court lift the stay of defendant's sentence because there is no legal basis for the stay under" the law, prosecutors wrote in a motion filed in U.S. District Court for the District of Columbia.

Bannon's lawyer, David Schoen, did not immediately respond to a request for comment on the motion.

Judge Carl Nichols later Tuesday ordered Bannon to respond to the prosecutors' motion by Thursday.

Bannon was convicted of two counts of criminal contempt of Congress in July 2022.

Judge Carl Nichols, who was appointed to the district court by former President Donald Trump, later sentenced Bannon to four months in jail but allowed him to remain free pending appeal.

In issuing that decision, Nichols wrote that Bannon's appeal "raises a substantial question of law that is likely to result in a reversal or an order for a new trial."

But on Friday, a three-judge panel on the U.S. Circuit Court of Appeals for the District of Columbia disagreed with Nichols' assessment and upheld Bannon's conviction in a unanimous ruling.

The panel rejected arguments by Bannon's lawyer that he was not guilty of contempt because his attorney had advised him not to comply with the House subpoena. The Jan. 6 select committee demanded his testimony and documents related to the Capitol attack, which was perpetrated by a mob of Trump's supporters.

But the panel ordered the appeals court clerk to withhold issuing the mandate of the ruling until seven days after any petition by Bannon's lawyer for a rehearing of the case was disposed of.

After that ruling, Bannon's lawyer Schoen said that he would ask for the appeal to be reheard by a panel made up of all the judges on the D.C. Circuit appeals court.

In his order Tuesday, Nichols told Bannon's lawyer to address the question of whether Nichols has the authority to lift his stay of Bannon's jail sentence, given the appeals court withholding the effect of its ruling pending such a petition for rehearing.

In Tuesday's court filing, the U.S. Attorney's Office for the District of Columbia told Nichols that because Bannon's appeal was rejected "on all grounds ... consequently, there is no longer a 'substantial question of law that is likely to result in a reversal or an order for a new trial.'"

"Under these circumstances ... the stay of the sentence must be lifted," prosecutors wrote.

In a footnote, prosecutors wrote that a federal district court in D.C. and the appeals court rejected a similar request by another former Trump aide, Peter Navarro, to stay a four-month jail sentence for contempt of Congress.

Navarro is currently serving his sentence in a minimum security federal prison in Miami.

In April, Allen Weisselberg, the former longtime chief financial officer of the Trump Organization, was sentenced to five months in jail after he pleaded guilty to perjury in testimony he gave in Trump's civil business fraud case in New York state court.

Weisselberg is currently serving his sentence at Riker's Island in New York City.
