The Senate Intelligence Committee is conducting its own investigation into Russian interference.
Who is George Papadopoulos and why is he important to the ongoing investigation?
Sessions appeared before the Senate Judiciary Committee during the former Alabama senator's confirmation hearing for attorney general.
The New York Times first reported that Page notified campaign officials about his meetings in Moscow, but the transcript, which is more than 200 pages long, discloses the names of those advisers - Tera Dahl and J.D. Gordon - and the identity of the Russian official, Dvorkovich.
In his testimony, Page said he has been interviewed by the Federal Bureau of Investigation about Russian Federation and the election four or five times this year. Page said he had mentioned his upcoming trip to Sessions, who at the time was a senior policy adviser to the Trump campaign.
Papadopoulos also told his superiors on the campaign that he was being offered "dirt" on Democratic rival Hillary Clinton and "off the record" meetings with Russian leaders - which, according to court documents, he was encouraged to pursue.
Page's July 2016 trip to Moscow drew attention during the campaign, particularly after WikiLeaks released emails that had been hacked from the Democratic National Committee a few weeks later and Russian Federation became a controversial campaign topic.More news: Fix Apple's Annoying IOS Update "i" Bug With These Two Tricks
Questioned by the committee, Page again denied meeting Sechin - but acknowledged he had met with other officials who work for Rosneft, the company Sechin leads, including the head of investor relations. "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". He maintained that his interaction with Dvorkovich consisted of a brief greeting, and that he had learned his views on the campaign while listening to Dvorkovich's public address.
In previous testimony in Congress, Sessions said he was "not aware of any of those" contacts between Russian officials and Trump campaign surrogates.
But prosecutors said they needed an independent appraisal of that Fifth Avenue property, since Manafort was claiming a fair-market value of the unit that appeared to exceed other outside estimates.
"Number one, there could be risks that the information is not comprehensive", said Page, under questioning from the panel's top Democrat, Adam Schiff of California. After the reports, Sessions went on to recuse himself from investigations related to the 2016 campaign.
In keeping with the Halloween spirit, the poll also found that Americans say that Trump is scarier than ghosts, vampires, witches, mummies, zombies and werewolves - but not scarier than the devil.
Only 7 percent of Trump voters say they believe that members of the campaign team colluded with Russian Federation.
