The investigation into alleged Russian interference in the United States elections has since been turned over to Special Prosecutor Robert Mueller.
Having previously pleaded guilty to misleading the Federal Bureau of Investigation about his contacts with Russian Federation agents offering dirt on Hillary Clinton to the campaign, Papadopoulos expressed remorse for his actions and received a more lenient sentence as a result.
Sen. Mark Warner of Virginia, the ranking Democrat on the Intelligence Committee conducting its own investigation into Russian meddling in the 2016 campaign, said Friday he believes Papadopoulos could be called to testify.
PAPADOPOULOS' attorney said Trump's efforts dwarfed his client's actions.
Papadopoulos says it has global implications and that "the truth matters".
Then, hedging a bit, he added: "I might have, but I have no recollection of doing so".

Breen told a rapt courtroom that Papadopoulos has already faced his penalty over the past year, and realized he needed to disavow the Trump administration in favor of the truth.
"No offence, but he was unsophisticated, he was naive and he was foolish", Breen said in court.
"We don't talk politics", he said.
Papadopoulos has asked the judge for extreme leniency.
Far from cooperating to energize the special counsel probe, prosecutors Jeannie Rhee, Andrew Goldstein and Aaron Zelinsky argued, Papadopoulos and his wife gave life to a false narrative about them and the seriousness of his offense.
Papadopoulos has been a central figure in the Russian Federation investigation since it began.
Papadopoulos initially lied to the Federal Bureau of Investigation about the timing of his interactions with the professor, suggesting they happened before he started working for Trump, while actually it was afterward. However, he did not submit to the judge any letters from friends and family that spoke to his personal character or supported his request.
Prosecutors had told Judge Randolph Moss that Papadopoulos should spend up to six months in prison. Mifsud allegedly told Papadopoulos that the Kremlin had "dirt" on the Democratic Party's nominee, Hillary Clinton, in the form of "thousands" of "emails of Clinton".
Papadopoulos was charged in July 2017.
"His arrest and prosecution served as notice to all involved that this was a serious investigation", the attorneys wrote.
Trump reacted to the sentencing in a tweet on Friday in which he appears to contrast the overall cost of the special counsel's investigation to Papadopoulos' 14-day sentence.
