Miami, Florida –

Donald Trump’s former White House trade adviser Peter Navarro reported to a Florida prison on Tuesday to begin serving a four-month sentence for contempt of Congress.

Navarro, 74, is the highest-ranking former Trump administration member to be jailed for the former Republican president’s attempts to overturn the results of the 2020 election.

Navarro was found guilty in September of two counts of contempt of court for refusing to comply with a subpoena to testify from a congressional panel investigating the Jan. 6, 2021, attack on the U.S. Capitol by Trump supporters.

Navarro, a Harvard-educated economist, had asked the U.S. Supreme Court to allow him to remain free while he appealed his conviction, but Chief Justice John Roberts on Monday rejected his last-ditch request.

Navarro, the mastermind of the “Green Bay Sweep” plan to prevent Congress from certifying the 2020 election results, will serve his sentence at a minimum-security federal prison in Miami.

He spoke to reporters in the parking lot before turning himself in.

“I am the first senior White House adviser in the history of our republic to be charged with this crime,” Navarro said. “When I walk into that prison today, the justice system itself will take a stand against the constitutional separation of powers and the Executive privilege hits hard.”

He claimed he was a victim of “the partisan weaponization of our justice system.”

“Everyone who puts me on the road to prison is a damn Democrat and a Trump hater,” Navarro said, adding that he would “go in there proudly and do the best I can .”

“I will take strength from this: Donald John Trump is the Republican nominee for president,” he said.

Navarro declined to testify before a House committee investigating the Jan. 6 attack on Congress and refused to provide documents to the panel.

A federal jury in Washington found him in contempt of court after a two-day trial.

Navarro is the second close Trump ally to be convicted of contempt of Congress for defying a House committee subpoena.

Steve Bannon, one of the architects behind Trump’s 2016 presidential campaign, was also found guilty of contempt of Congress.

Bannon was sentenced to four months in prison in January but remains free pending an appeal.

Trump is scheduled to go on trial in Washington on March 4 on charges of conspiring to overturn the results of the election won by Democrat Joe Biden.

However, his trial has been put on hold until the Supreme Court hears Trump’s argument that as a former president he is immune from criminal prosecution.

The Supreme Court is scheduled to hear arguments on the immunity case on April 25.

Trump, 77, was impeached by the House for a second time after the Capitol riot – he was charged with inciting insurrection – but was acquitted by the Senate.
