Steve Bannon has to go to prison for defying Congress by a certain date.

Steve Bannon, a prominent figure and long-time ally of former President Trump, is set to begin serving a four-month prison sentence in Connecticut on Monday. This sentence comes as a result of Bannon’s contempt for defying a subpoena in the congressional investigation into the U.S. Capitol riot on January 6, 2021.

Despite being allowed to remain free for nearly two years while he appealed the contempt charges, U.S. District Judge Carl Nichols eventually revoked Bannon’s bail and ordered him to report to prison by July 1 after an appeals court panel upheld his convictions. The Supreme Court then rejected his final appeal, leading to his upcoming prison term.

In an emergency motion filed last month, Bannon’s new lawyer, R. Trent McCotter, argued that the government’s intention to imprison Bannon leading up to the November election would prevent him from playing a significant role as an advisor on important campaign issues. The motion highlighted the political implications of Bannon’s prosecution, stating that he is a high-profile political commentator and strategist whose views often clash with the administration prosecuting him.

Bannon was found guilty of two counts of contempt of Congress: one for refusing to cooperate with the Jan. 6 House Committee’s deposition, and another for failing to provide documents related to his involvement in Trump’s attempts to overturn the 2020 election results.

Defense attorneys have raised concerns that the case raises critical issues that should be reviewed by the Supreme Court, including the argument that the subpoena issued to Bannon was invalid due to Trump’s claim of executive privilege. Prosecutors, on the other hand, insist that Bannon had already left the White House by that time, and Trump had never invoked executive privilege during the committee hearings.

As Bannon prepares to surrender to prison, the same day coincides with the Supreme Court’s decision on a case involving Trump’s potential immunity from prosecution in connection with the election results dispute.

Meanwhile, Bannon’s appeal process will continue, and Republican House leaders have shown support for challenging the legitimacy of the Jan. 6 committee, suggesting that Bannon’s subpoena may be deemed invalid.

Notably, another former Trump aide, trade adviser Peter Navarro, has also been convicted of contempt of Congress and began serving his four-month sentence in March, following the Supreme Court’s denial of his request to delay the sentence.

In addition to his current legal challenges, Bannon is also facing separate criminal charges in New York for allegedly defrauding donors who contributed to a project aimed at constructing a border wall between the U.S. and Mexico. Bannon has pleaded not guilty to charges of money laundering, conspiracy, fraud, and more, with his trial postponed until at least the end of September.

As the legal saga surrounding Steve Bannon continues to unfold, the political world watches closely to see the implications and outcomes of his case.
