But he does not recall the details of what Mr Papadopoulos said, Mr Sessions testified before the House Judiciary Committee.
Sessions also said on Tuesday he did not challenge a statement by another campaign foreign policy adviser, Carter Page, that he told Sessions in a brief encounter that he was about to leave for Moscow. "We are providing you notice in advance because we expect you to respond".
Sessions has previously told Congress he was unaware of any Trump campaign contacts with Russian Federation, leading Democrats on Tuesday to accuse him of lying under oath. In particular, they will "make recommendations as to whether any matters not now under investigation should be opened", or whether a special counsel will be needed, states the letter, which was delivered ahead of a committee oversight hearing at which Sessions will appear on Tuesday.
Sessions has faced repeated questions from senators about his role in the campaign and the investigation into Russian meddling in the U.S. election.
Papadopoulos, who pled guilty to lying to the Federal Bureau of Investigation about his contacts with Russia, told the Trump campaign meeting that he had connections with Moscow and could help arrange a meeting between Trump and Russian President Vladimir Putin, according to court documents.
Sessions' testimony appears likely to keep the controversy over Russian Federation boiling as Special Counsel Robert Mueller accelerates his investigation into possible collusion between the Trump campaign and Russian Federation.

World class Sergio Aguero heads Argentina to victory over Russian Federation
Meanwhile, Argentina coach Jorge Sampaoli was pleased with his side's dominance over Russian Federation in the friendly game. He singled out Aguero for creating scoring opportunities despite a lack of space offered by Russia's defensive setup.
Congressional lawmakers pressed the United States' top law enforcement official on his recollection of interactions between President Donald Trump's election campaign and Russian officials. He said he mentioned in passing to Sessions that he was preparing to visit Russian Federation and Sessions "had no reaction whatsoever".
The New York Times reported Tuesday that Pirro met with President Trump in early November during which she "excoriated" the attorney general for not investigating Clinton.
The attorney general confirmed that he has asked senior federal prosecutors to look into a host of issues involving former secretary of state and Trump's election rival, Democrat Hillary Clinton, including the sale of a uranium company to Russian Federation. The move, detailed in a letter to Judiciary Chairman Bob Goodlatte, comes after Trump has criticized his Justice Department for not doing more investigation of his former political rival. That deal involved selling part of a Canadian-based mining company to Rosatom, resulting in the company acquiring control over 20 percent of America's uranium supply.
The hearing comes after a year where Sessions has been under repeated pressure from the President to launch investigations into Clinton - including on the Uranium One deal approved while she was secretary of state - and has been under fire from congressional Democrats about his answers on Russian Federation and push end the DACA program for undocumented immigrants brought to the United States as children, among other issues.
Democrats have accused Republicans of launching a spurious investigation of Clinton, the 2016 Democratic presidential candidate, to divert attention from Special Counsel Robert Mueller's investigation into alleged links between President Donald Trump's presidential campaign and Russian Federation.
