As reported by Censor.NET referring to The Washington Post citing Justice Department officials.
Then Republican Senator Jeff Sessions spoke twice last year with Russia's Ambassador to the United States Sergey Kislyak. One of the meetings took place in September, at the height of what U.S. intelligence officials say was a Russian cyber campaign to upend the U.S. presidential race.
The fact caused an outcry after Sessions said he had not had any contacts with Russia's representatives during the 2017 U.S. presidential campaign, speaking at his confirmation hearing to become attorney general.
As attorney general, Sessions oversees the Justice Department and the FBI, which have been leading investigations into Russian meddling and any links to Trump's associates.
"It is now clearer than ever that the attorney general cannot, in good faith, oversee an investigation at the Department of Justice and the FBI of the Trump-Russia connection, and he must recuse himself immediately," Democratic Senator Al Franken told The Washington Post.
Another Democratic Senator Ron Wyden, a senior member of the Senate Intelligence Committee, said on Twitter late Wednesday that "we need a special counsel to investigate Trump associates' ties to Russia."
As reported by AP, in a statement later on March 1, Sessions said: "I never met with any Russian officials to discuss issues of the campaign. I have no idea what this allegation is about. It is false."
The Russian embassy in Washington declined to comment on reports about possible contacts between Sessions and Kislyak, according to Interfax.
Last month, Trump national security adviser Michael Flynn resigned after it emerged he had discussed Russian sanctions in a phone conversation with the Russian ambassador in Washington.
