On Wednesday, The Washington Post reported that Sessions met with Russian officials - including Russian Ambassador Sergey Kislyak - in July and September, a time when us intelligence officials say Russia was trying to sway the United States presidential election.
The Federal Bureau of Investigation works under Sessions' Department of Justice.
In November, Mr. Trump's spokeswoman told the Associated Press "there was no communication between the campaign and any foreign entity".
Trump wanted to know the logic behind Sessions' decision to recuse himself.
Exactly three weeks after assuming office, President Donald Trump's pick to lead the Department of Justice was forced to recuse himself from any investigation involving the campaign or its ties to Russian Federation. "The integrity of our democratic institutions is at stake, and the American people deserve the truth", Bennet said in a statement issued by his office.
As we learned last night, it would appear as if Jeff Sessions' claims during his Senate confirmation hearing that he did not have any contact with Russian officials may not have been exactly true.
"I think we need to understand what role if any he will have in the investigation", Gardner said, adding that he had "full confidence" in the FBI.
The newspaper said J D Gordon, who was the Trump campaign's director of national security, and Carter Page, another member of the campaign's national security advisory committee, both said they met the ambassador.
The move comes after the Justice Department confirmed Wednesday that Sessions spoke twice past year with Ambassador Sergey Kislyak while serving as a prominent supporter and adviser to Trump's presidential campaign. "They lost the election and now, they have lost their grip on reality", Trump said in his statement late Thursday.
During the Senate hearings earlier this year, when asked what he would do if he learned a member of Trump's campaign had communicated with the Russian government over the course of the 2016 campaign, Sessions responded: "I'm not aware of any of those activities".
While the Hillary Clinton campaign says no one there met with the ambassador, he did visit the Obama White House 22 times.
Bannon was reportedly on the way to Mar-a-Lago Saturday "for an EO launch meeting", along with Justice Department officials.
