Jury selection begins on Monday in the criminal trial of Steve Bannon, a former presidential aide to Donald Trump, who faces charges that he defied a congressional subpoena from the committee investigating the January 6th, 2021, attack on the US Capitol by Mr Trump's supporters.
Mr Bannon, 68, is facing two misdemeanour counts of contempt of Congress after he declined to provide testimony or documents to the House of Representatives committee.
Mr Bannon has unsuccessfully tried to persuade US District Judge Carl Nichols to delay his trial, arguing that the committee's high-profile televised hearings could make it harder for him to have a fair and impartial jury.
The committee presented evidence in a televised hearing last week that Mr Bannon spoke with Mr Trump at least twice on January 5th, the day before the Capitol attack.
The committee also played a clip of Mr Bannon saying "all hell is going to break loose tomorrow" on a right-wing talk show that day. He made those comments after his first call with Mr Trump, the committee said.
Another hearing could be held this week, while the trial continues.
After Mr Bannon was first charged in the case, he claimed he was unable to comply with the committee's request because the materials were covered by a legal doctrine known as executive privilege that keeps presidential communications confidential.
Judge Nichols has ruled that Mr Bannon cannot use executive privilege as a defence in his case, and he also cannot claim he relied on his attorney's advice when he declined to testify or provide records.
Mr Trump told Mr Bannon earlier this month he was waiving any executive privilege claim, and Mr Bannon has since offered to testify before the committee.
Last week, Judge Nichols left open the possibility that Mr Bannon could potentially present evidence of his recent offer to cooperate with the panel to the jury as a defence.
