But Papadopoulos' attorney, in a court filing this month, said that Sessions "stated that the campaign should look into" a Putin-Trump meeting - something that Papadopoulos himself reiterated in media interviews over the last few days.
To cap off yet another turbulent week inside the administration of President Donald Trump, a former advisor whose contacts with Russians set off the investigation into possible collusion with Moscow was jailed on Friday for lying to the FBI.
He pleaded guilty in October 2017 to lying to federal investigators about his contacts with Joseph Mifsud, a London-based professor who supposedly told him in 2016 that Russian Federation had damaging information on Hillary Clinton, Mr. Trump's Democratic opponent.
Mr. Sessions has testified that he pushed back on the idea.
"I have been asked this a million times, and here's the reality", Papadopoulos said.
"I understood that there was an incipient investigation into Russian interference in the 2016 election, and I found myself as somebody who worked incredibly hard over the past year in the campaign to actually have candidate Trump be elected". He was open to the idea and he deferred of course to then senior Sen.More news: 1.5m flee homes as deadly hurricane heads towards US
"I thought it would be a nice photo op", Papadopoulos said on ABC's "The View" Tuesday of the prospect of a Trump-Putin meeting.
"All I can say is that my testimony might have helped move something towards that, but I have no idea".
"As far as I remember, I absolutely did not share this information with anyone on the campaign", the ex-Trump campaign aide told CNN's Tapper.
Ahead of his sentencing, Papadopoulos asked the court to give him probation for his charge of lying to the Federal Bureau of Investigation, claiming he was "young" and lied out of "misguided loyalty to his master".
Papadopoulos finally said that he was "remorseful" for how things had turned out, but claimed that he had never done anything without the knowledge of senior Trump campaign officials.

Papadopoulos also lamented his decision to not immediately approach USA intelligence officials with information on his meeting with Misfud, calling it "the biggest regret I actually have".
"My recollection differs from Jeff Sessions'", Papadopoulos told Stephanopoulos.
"The president of the United States hindered this investigation more than George Papadopoulos ever could", his lawyer said.
He said Papadopoulos' deception required investigators to scour more than 100,000 emails and gigabytes of data to reconstruct the timeline of his contacts with Russians and Russian intermediaries.
So far, campaign chairman Paul Manafort; Mr Trump's personal lawyer Michael Cohen; Deputy campaign manager Rick Gates and National security adviser Michael Flynn have all pled or been found guilty.More news: Trump Jr.: Group Trump Trusts 'Much Smaller' After Op-Ed, Woodward Book
