In a last-ditch effort to avoid being sent to prison, former Trump White House official Peter Navarro has appealed to the US Supreme Court. Navarro, who was convicted of contempt of Congress for refusing to cooperate with a congressional investigation into the January 6 attack on the US Capitol, is scheduled to report to federal prison on Tuesday.

The appeal comes after an appeals court concluded that Navarro's conviction was not likely to be overturned. Navarro had argued that he couldn't cooperate with the investigation because former President Donald Trump had invoked executive privilege. However, Federal judge Amit Mehta, appointed during Barack Obama's presidency, ruled that Navarro failed to provide evidence that Trump had actually invoked executive privilege.

Meanwhile, the Supreme Court is also set to hear arguments on whether Trump himself has presidential immunity from charges related to alleged interference in the 2020 election, which he lost to Joe Biden. This adds another layer of intrigue to Navarro's case, as it further highlights the ongoing legal battles surrounding Trump's presidency.

Navarro's emergency application to the Supreme Court comes on the heels of a similar situation involving former Trump White House chief strategist Steve Bannon, who was also convicted of congressional contempt charges. Bannon received a four-month sentence but was allowed to remain free pending appeal by federal judge Carl Nichols, who was appointed by Trump.

As an economist and trade adviser to Trump, Navarro was found guilty of defying a subpoena for documents and a deposition from the House committee investigating the January 6 attack. He was also found to have promoted Trump's baseless claims of electoral fraud that allegedly denied him victory against Biden. As a result, Navarro was sentenced to four months in prison.

With the fate of his impending prison sentence hanging in the balance, Navarro's appeal to the Supreme Court will be closely watched. The decision will not only impact his personal future but could also set legal precedence regarding executive privilege claims and the accountability of high-ranking government officials.
