A federal judge in the United States has ordered Steve Bannon, a former top adviser to ex-President Donald Trump, to report to prison by July 1 to serve his four-month sentence for contempt of Congress.

US District Judge Carl Nichols’s order on Thursday came after a federal appeals court last month rejected Bannon’s bid to overturn his conviction.

Bannon was convicted of contempt in July 2022 for defying a subpoena to testify before a congressional panel that investigated the January 6, 2021, attack on the US Capitol by a mob of Trump supporters.

Thursday’s decision means Bannon, 70, will likely be behind bars for a critical stretch of the US presidential campaign as Trump faces Democratic President Joe Biden in what is expected to be a tight November election.
