The Justice Department is asking a federal judge to impose a prison sentence on former Trump adviser Steve Bannon.

Former Trump adviser Steve Bannon should begin serving a four-month prison sentence now that a federal appeals court has upheld his conviction for contempt of Congress, the Justice Department told a judge Tuesday federal.

U.S. District Judge Carl Nichols, who presided over Bannon’s trial, had suspended Bannon’s sentence while an appeal of his conviction was pending. He gave Bannon until Monday to respond to the DOJ’s request, extending an earlier deadline following a delay motion from the defense team.

Bannon was convicted in July 2022 by a federal jury of two counts of contempt of Congress for defying a subpoena by the House Select Committee on January 6 as part of its investigation into the attack of 2021 against the US Capitol.

The Justice Department said in its court filing that a convicted person must report to serve their prison sentence unless the defendant can establish that “the appeal is not intended to delay and raises an important question of law or fact likely to result in reversal.”

“The D.C. Circuit denied defendant’s appeal on all grounds, including the primary argument on appeal: the mental state required for a contempt of Congress violation,” the Justice Department wrote.

The appeals court’s unanimous decision was a victory for Congress, potentially paving the way for how others will be held accountable if they defied a congressional subpoena.

It remains unclear when Bannon is expected to report to prison.
