Trump pardons former adviser Flynn, who pleaded guilty in Russia probe

U.S. President Donald Trump on Wednesday pardoned his former national security adviser Michael Flynn who had pleaded guilty to lying to the FBI during the investigation into Russian meddling in the 2016 presidential election.

"It is my Great Honor to announce that General Michael T. Flynn has been granted a Full Pardon. Congratulations to @GenFlynn and his wonderful family, I know you will now have a truly fantastic Thanksgiving!" Trump wrote on Twitter.

A retired Army general, Flynn pleaded guilty in 2017 to lying to the FBI about interactions he had with Russia's ambassador to the United States in the weeks leading up to Trump's inauguration in January 2017.

He has since sought to withdraw the plea, arguing that prosecutors violated his rights and duped him into a plea agreement. His sentencing has been deferred several times.

It was the highest-profile pardon granted by Trump since he took office. Among others, the Republican president has pardoned Army personnel accused of war crimes in Afghanistan and Joe Arpaio, a former Arizona sheriff and hardliner against illegal immigration.

Flynn served as Trump's first national security adviser but the president fired him in early 2017 after only 24 days as a controversy broke over the former general's contacts with then Russian Ambassador Sergei Kislyak.

Flynn was one of several former Trump aides to plead guilty or be convicted at trial in former Special Counsel Robert Mueller's investigation into Moscow's interference in the 2016 U.S. election to boost Trump's candidacy. Russia denied meddling.

Trump in March said he was strongly considering a full pardon for Flynn. He said the FBI and Justice Department had "destroyed" Flynn's life and that of his family, and cited an unspecified, unsubstantiated report that they had lost records related to Flynn.

Flynn was supposed to help cooperate with the government as part of his plea deal. But he later switched lawyers and tactics, arguing that prosecutors in the case had tricked him into lying about his December 2016 conversations with Kislyak.

The Justice Department has repeatedly denied allegations of prosecutorial misconduct, and U.S. District Court Judge Emmet Sullivan rejected all of Flynn's claims in December 2019.

Federal prosecutors had asked the judge in January to sentence Flynn to up to six months in prison, arguing in a court filing that "the defendant has not learned his lesson. He has behaved as though the law does not apply to him, and as if there are no consequences for his actions."

Flynn also served as head of the Pentagon's Defense Intelligence Agency but was forced out in 2014 in part due to his management style and opinions on how to fight Islamist militancy.

He joined the Trump 2016 election campaign and at the Republican National Convention that year he led supporters in chants of "Lock her up," in reference to Democratic candidate Hillary Clinton.

Other former Trump aides were convicted of federal crimes following the Russia inquiry. Trump's longtime friend and adviser Roger Stone was sentenced on Feb. 20 to three years and four months in prison for obstruction of justice, witness tampering and lying to lawmakers investigating the Russian election interference.

Paul Manafort, Trump's former campaign chairman, was sentenced last year to 3-1/2 years in prison after being convicted of unlawful lobbying and witness tampering, which combined with a sentence in a related case equaled a term of more than seven years behind bars.

Trump, defeated in a presidential election on Nov. 3, is due to leave the White House on Jan. 20 when President-elect Joe Biden takes office.
