But Sessions, who was a top surrogate for Trump during the campaign, did not disclose these discussions despite a persistent set of questions from Democrats and some Republicans about Russian Federation during multiple hearings on Capitol Hill.
"He now needs to come back before the Committee, in person, under oath, to explain why he can not seem to provide truthful, complete answers to these important and relevant questions", Leahy, a former chairman of the Judiciary Committee, told The New York Times. At least two Democratic members of the Senate judiciary committee, Al Franken of Minnesota and Patrick Leahy of Vermont, have asked the FBI to investigate whether Sessions committed perjury during his confirmation hearings.
Franken asked Sessions during his confirmation hearing on Jan 10 what he would do "if there is any evidence that anyone affiliated with the Trump campaign communicated with the Russian government in the course of this campaign".
Rep. Mike Conaway, R-Texas, who is in charge of the committee's Russian Federation investigation, confirmed to CNN that Page gave such testimony, but minimized its meaning.
Page told ABC News he "mentioned in passing" to Sessions the June 2016 Russian Federation trip he had planned, and "that I happened to be planning to give a speech at a university in Moscow".
In addition to Leahy and Blumenthal, Senators Al Franken (Minn.) and Chuck Schumer (NY) are calling for the attorney general to testify.
"We must get to the bottom of what happened so that we can prevent it from happening again, and I am deeply troubled that this newest revelation strongly suggests that the Senate - and the American public - cannot trust your word", Franken wrote.
Asked who else was informed, Page played coy, saying, "It will come out". "The saddest thing is, because I am the president of the United States, I am not supposed to be involved with the Justice Department".
In a letter to Sessions on Thursday, Sen. A guy he had never met before grabs him, 'Hey, I'm out on the team.
A Justice spokesperson declined to comment.
In an eight-page letter sent to Sessions Thursday, Franken called on the attorney general to explain why he didn't mention the Papadopoulos exchange while testifying before the Senate.
"He may still have technically answered the question correctly", said Representative Jerrold Nadler, a New York Democrat. In testimony to the Senate Judiciary committee, Sessions has denied knowing anything about contacts between the campaign and Russians or Russian government intermediaries.
Papadopoulos was named by Trump as a member of his foreign policy advisory panel in March 2016, when the candidate was trying to bolster his credentials as he moved to secure the Republican nomination for president. "I think the Democrats might want to be careful what they ask for".
Sessions replied, "I have not seen anything that would indicate collusion with the Russians to impact the campaign".
"I had a very brief hello to a couple of people".
