The campaign was certainly aware of his connections to Russia because Papadopoulos suggested using them to set up a meeting between Donald Trump and Russian President Vladimir Putin at a March 2016 meeting of the foreign policy team with Trump present.
The open hearing, tentatively scheduled for November 14, is part of the committee's regular oversight of the Justice Department, but Russian Federation appears nearly certain to be a topic.
It is still unclear whether Papadopoulos, who pleaded guilty last month to lying to the Federal Bureau of Investigation, told members of the Trump campaign about the emails.
The committee's Republican majority did not comment on the transcript Monday.
One of them was Jeff Sessions, then an Alabama senator and early Trump endorser and now the attorney general.
Schiff called the Russian links to Papadopoulos and Page two parallel efforts by the Trump campaign to make contacts with Russian interests.
MR. SCHIFF: You've also testified that, apart from him, you met no one from the Presidential administration, and yet on July 8, of past year, you wrote in an email to the campaign that you had incredible insights and outreach that you received from Russian legislators and senior members, plural, of the Presidential administration. "It's important to remember that Carter Page and George Papadopoulos were peripheral members of a relatively peripheral advisory committee", he said.
Page has often been contradictory about whom he met on the trip, but his testimony Thursday was under oath. Hicks is now the White House communications director. "In his testimony, however, he was forced to acknowledge that he communicated with high level Russian officials while in Moscow, including one of Russia's Deputy Prime Ministers".
For months, Page has denied meeting with Russian government officials while in Moscow.
And Page told the committee about another foreign trip he took during the campaign, a long weekend he spent in Budapest where he said he met with Hungary's ambassador to the United States and other Hungarian officials. Their conversation, he told investigators, was not about coordination with Russian Federation on the campaign, but largely limited to an exchange of pleasantries.
Attorney General Jeff Sessions will appear in front of a House Judiciary Committee panel on November 14, where he is expected to face questions about communications between the Russian government and President Trump's election campaign, Reuters reports.
He wrote to Gordon and Tera Dahl, a former columnist at Breitbart, that he would send them a memo "regarding some incredible insights and outreach I've received from a few Russian legislators and senior members of the presidential administration here".
Page described the conversation to CNN after he finished talking to the House intelligence committee.
Page also acknowledged to members of Congress that he has had at least four meetings with the FBI related to the Russian Federation investigation.
The idea that the Trump campaign coordinated with Russian operatives to hack into and disseminate Democrats' emails has been a core theory of the collusion allegation.
