Prosecutors say Papadopoulos was solicited by a professor with ties to Russian intelligence, Joseph Mifsud, who told the young Trump aide that the Russians possessed incriminating information about Hillary Clinton in the form of "thousands of emails" - before it was widely and publicly known that Russia had stolen Democratic emails.
US District Judge Randolph Moss said that Papadopoulos' deception was "not a noble lie" and that he had lied because he wanted a job in the Trump administration and didn't want to jeopardize that possibility by being tied to the Russian Federation investigation.
According to Bloomberg, the DNC said it believed all of the defendants in the case had been served, with the exception of Mifsud.
Told the campaign's priority was to improve relations with Russian Federation, within weeks he made contact with a mysterious professor, Joseph Mifsud, who touted links to the Kremlin. Instead, prosecutor Andrew Goldstein said he made "at best grudging efforts to cooperate, and we don't think they were substantial or significant in any regard".
"The candidate (Trump) gave a nod, but did not commit either way", he said.
Also in court, his lawyer, Thomas Breen, criticized Mr. Trump for calling the Russian Federation probe fake news and a witch hunt. And, the prosecutors add, Papadopoulos has been hard for them to handle since he was arrested in July 2017.
Prosecutors argued that Papadopoulos' repeated lies during a January 2017 interview with investigators stymied the inquiry at a critical moment.
Papadopoulos, a young oil and gas consultant, was the first Trump official to plead guilty and cooperate in the investigation into Russian interference in the 2016 USA election.
"The president of the United States hindered this investigation more than George Papadopoulos ever could", Breen told the judge.
That account conflicts with what Sessions, now attorney general, testified before Congress.
Outside the courthouse Friday, Breen said Papadopoulos didn't recall ever telling anyone in the campaign about the fact that Russian Federation had dirt on Clinton in the form of emails. More accurately, Papadopoulos hemmed and hawed, and finally settled on, "I might have, but I have no recollection of doing so".
USA investigators were only alerted to Papadopoulos's activities in mid-2016 after he told Australia's ambassador to London, Alexander Downer, about his talks with Mifsud during a late-night drinking session in a London pub.
The Chicago native was a London-based petroleum analyst before he joined the Trump campaign in March 2016 as a volunteer foreign policy adviser. "Earlier on Friday Trump, who dismisses the Mueller probe as a 'witch hunt", had denied knowing him. He said his client doesn't recall telling anybody connected with the Trump campaign about Mifsud's offer of Clinton dirt. Lawyers for Papadopoulos had requested probation, saying he lied not to impede investigation but "to preserve a perhaps misguided loyalty to his master".
"We were hoping for no jail time but two weeks is OK", Maria Stamatopoulos said.
