For weeks after the 2020 election had been referred to as, Peter Navarro, a White House adviser to President Donald J. Trump, labored intently with different senior aides to maintain Mr. Trump in energy for a second time period.

After being subpoenaed last year by the House committee investigating the Jan. 6, 2021, riot, which sought to study extra about these efforts, Mr. Navarro refused to conform, insisting that Mr. Trump had directed him to not cooperate and dismissing the subpoena as “illegal” and “unenforceable.”

Now, after greater than a 12 months of authorized wrangling, Mr. Navarro, 74, will defend these claims in a trial that begins Tuesday, when jury choice is anticipated to start in Federal District Court in Washington. The case facilities on a comparatively easy query: whether or not he confirmed contempt for Congress in defying the House committee’s request for paperwork and testimony.

The trial itself could also be comparatively quick, and if Mr. Navarro had been to be convicted on the 2 counts of contempt of Congress he’s charged with, he might withstand a 12 months in jail and a wonderful of as much as $100,000 for every rely.

Since Mr. Navarro was indicted in June of last year, he has maintained that he’s protected by the former president’s claim of executive privilege.

Prosecutors intend to argue that Mr. Navarro refused of his personal volition and that neither Mr. Trump nor his attorneys have confirmed whether or not Mr. Navarro sought or acquired his approval.

The decide within the case, Amit P. Mehta, has already dealt a blow to Mr. Navarro, ruling that he can not depend on govt privilege as a pillar of his protection. He refused to dismiss the case after concluding that Mr. Navarro had failed to supply convincing proof that he and Mr. Trump ever mentioned his response to Congress.

Describing Mr. Navarro’s protection as “pretty weak sauce,” Judge Mehta emphasised that he had offered no written communications or perhaps a “smoke signal” that will bolster his rivalry.

“I still don’t know what the president said,” Judge Mehta stated. “I don’t have any words from the former president.”

“I don’t think anyone would disagree that we wish there was more here from President Trump,” Mr. Navarro’s lawyer, Stanley Woodward Jr., replied.

Still, outdoors of courtroom, Mr. Navarro has continued to border the case as a elementary dispute between the legislative and govt branches, calling the fight over executive privilege “open questions” within the regulation and pledging to attraction.

Mr. Navarro is one in all two Trump aides to face legal prices after the House committee’s investigation. Stephen Ok. Bannon, one other of Mr. Trump’s senior advisers, was convicted last summer on two counts of contempt of Congress and sentenced to four months in prison.

After the 2020 election, Mr. Bannon and Mr. Navarro concocted a plan, referred to as the Green Bay Sweep, geared toward delaying certification of the result of the election. The strategy concerned persuading Republican lawmakers to halt the counting of Electoral College votes on Jan. 6 by repeatedly difficult the ends in numerous swing states.

When the House committee investigating the Jan. 6 assault issued a subpoena, Mr. Bannon equally refused to conform.

Others in Mr. Trump’s interior circle had been much less combative in resisting the panel’s efforts.

Two of Mr. Trump’s advisers, Roger J. Stone Jr. and Michael T. Flynn, finally appeared earlier than the committee however declined to reply most of its questions by citing their Fifth Amendment rights in opposition to self-incrimination. Mr. Trump’s remaining chief of workers, Mark Meadows, and his deputy, Dan Scavino, negotiated the phrases of their responses to subpoenas, offering paperwork however not testimony. None of the 4 males confronted legal prices.

The submitting of prices in opposition to Mr. Navarro was broadly seen as proof that the Justice Department was keen to behave aggressively in opposition to one in all Mr. Trump’s high allies because the House scrutinized the actions of the previous president and his advisers and aides within the occasions main as much as and through the Capitol assault.

The trial might additionally shed new mild on Mr. Navarro’s communications with the White House at key moments throughout Mr. Trump’s remaining days in energy.

One attainable witness for the protection is Liz Harrington, a communication aide for Mr. Trump who helped unfold false claims of election irregularities within the months after the 2020 election. Ms. Harrington had been set to testify final week about Mr. Navarro’s claims of govt privilege, however might as a substitute present written testimony in regards to the extent of Mr. Navarro’s contact with Mr. Trump and his aides.
