The judge had planned a harsher sentence but said he was moved by Papadopolous' words of contrition.
It comes ten months after Papadopoulos pleaded guilty to lying to the Federal Bureau of Investigations (FBI), which at the time was leading the probe into allegations that Russian Federation interfered in the 2016 USA presidential elections.
Papadopoulos pleaded guilty in October to lying to the Federal Bureau of Investigation about meetings with individuals closely associated with the Russian government during the campaign.
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.
In court papers, Breen wrote that during a March 2016 meeting attended by Papadopoulos, Trump nodded with approval at the idea, and then-Senator Jeff Sessions "appeared to like" it and said the campaign "should look into it".
In his pre-sentencing statement, Papadopoulos admitted lying to FBI investigators in January 2017 but said it had been out of a desire to protect his career and a naive loyalty to the Trump administration. He hasn't returned since.
George Papadopoulos, 31, told the court in Washington DC he was a "patriotic American" who made a mistake by lying. "I hope you think of your sentence as the beginning of that second chance". With his constant cries of "fake news", Trump has "hindered this investigation more than George Papadopoulos ever did", Breen said.
That account conflicts with what Sessions, now attorney general, testified before Congress. He was the first known Trump campaign official to cooperate with the special counsel into possible conspiracy between the Trump campaign and the Kremlin.

Communities along the coast provided sand and bags, and many hustled to protect their properties ahead of the storm. Winds from the storm caused at least one death in Florida when a tree fell onto a mobile home in Escambia County.
As part of his sentence, Papadopoulos also will have one year of court supervision, 200 hours of community service and was fined $9,500. He gave false statements about his contacts to the FBI, which the FBI said impeded their investigation into the extent that Russian meddling may have worked its way into the campaign.
As noted by USA Today, authorities thought that Papadopoulos could serve as a key informant, but it quickly became clear that was not the case. The case was kept under seal for three weeks after his guilty plea and made public only when Mueller announced the indictments of campaign chairman Paul Manafort and his top deputy, Rick Gates, for money laundering, illegal lobbying and other charges unrelated to the election.
A hearing in that lawsuit is scheduled for next week in federal court in NY.
"I made a awful mistake, but I am a good man who is eager for redemption", Papadopoulos said at his sentencing hearing.
Friday was his first public court appearance since he pleaded guilty in October, 2017, to lying to the Federal Bureau of Investigation while the case was still sealed.
But in a court filing last month, prosecutors said Papadopoulos ultimately did little to aid their work.
"Despite constant attacks by the President and his allies, Special Counsel Robert Mueller and his team have once again demonstrated that they are conducting a serious, professional investigation into the Trump campaign's contacts with Russians during the 2016 election", Warner said in a statement.
At that meeting, Mr. Papadopoulos proposed brokering a meeting between Mr. Trump and Russian President Vladimir Putin.
