Federal prosecutors are due to make their final pitch to jurors on Friday to convict Steve Bannon, Donald Trump’s former presidential adviser, on charges of contempt of Congress for defying a subpoena by the committee investigating last year’s attack on the US Capitol by supporters of the-then president as they sought to overturn his election defeat by Joe Biden.

The prosecution and defense are expected to deliver closing arguments to the 12-member jury in federal court, with deliberations expected to begin afterward.

The defense rested its case on Thursday without calling any witnesses after the prosecution rested on Wednesday, having called two witnesses over two days.

Bannon, 68, has pleaded not guilty to two misdemeanor counts after rebuffing the House of Representative select committee’s subpoena requesting testimony and documents as part of its inquiry into the January 6, 2021, rampage by Trump supporters trying to stop the US Congress officially certifying Democrat Biden’s win over Republican Trump.

Bannon had promised in out-of-court bluster to fight his case vigorously and make it the “misdemeanor from hell” for the authorities, but he ultimately made no presentation to the court, as the Daily Beast reported.

Prosecutors said they expect their arguments on Friday to last about 30 minutes, plus 15 for rebuttal. The defense said it plans to take roughly the same amount of time to make its arguments.

Bannon was barred from arguing that he believed his communications with Trump were subject to a legal doctrine called executive privilege that can keep certain presidential communications confidential. The judge also prohibited Bannon from arguing that he relied on legal advice from an attorney in refusing to comply with the congressional subpoena.

Bannon’s primary defense in the trial was that he believed the subpoena’s deadline dates were flexible and subject to negotiation between his attorney and the committee.

The main prosecution witness was Kristin Amerling, a senior committee staff member. She testified on Wednesday that Bannon disregarded the subpoena’s two deadlines, sought no extensions and offered an invalid rationale for his defiance – a claim by Trump involving a legal doctrine called executive privilege that can keep certain presidential communications confidential.

Bannon has spoken only once in court throughout the trial. He said: “Yes, your honor,” when the judge asked if he agreed not to testify.

Outside court on Thursday, Bannon said: “One last thing. I stand with Trump and the constitution.”
