And asked about Trump's own contention that he fired Comey with the Russian Federation probe in mind, and regardless of any recommendation from anyone else, Sessions said: "I guess I'll just have to let his words speak for themselves".
Here are the top five things we learned.
Sessions got angry again when Wyden pressed Sessions to explain what facts might be "problematic "about his involvement in the Russian Federation probe, as Comey suggested".
Comey testified that after what he called a "disturbing" private talk with Trump, he went to Sessions.
"I'm not able to comment on conversations with high officials within the White House", Sessions said. "I think he's weighing that option", Chris Ruddy, chief executive of Newsmax, told the PBS News Hour, speaking of Trump. As Trump tried to shoo everyone out to talk alone with Comey, Sessions lingered, in Comey's account.
"Why don't you tell me?"
"It's conceivable that that occurred", Sessions said.
"Sir, sir, I have just a few minutes", she interrupted again, smiling.
Later, under an intense grilling from Sen. This was a very important corroboration of James Comey's testimony.
"I am not stonewalling", Sessions replied, saying he was simply following Justice Department policy not to discuss confidential communications with the president. I.e. Jim, looks like you've got this in hand.
Stewart said there is proof of President Barack Obama's administration "unmasking" - revealing a US citizen's identity in surveillance of foreign officials - and leaking of classified information, which should be prosecuted. Kamala Harris, D-Calif. "I don't want to be rushed this fast". Do one or the other, you know?
Russian Federation has denied any such interference, and Trump has denied any collusion by his campaign with Moscow.More news: United Kingdom general election 2017: 208 women MPs, a proud record for Parliament
The attorney general on March 2 recused himself from the FBI investigation into Russia's role in the election, saying he felt he was required to do so because he had been a prominent figure in Trump's campaign.
Comey contended last week that he specifically asked Sessions not to allow him to be left alone with Trump. Days after that, Sessions also corrected his confirmation hearing testimony to inform the committee about his two meetings with Kislyak. In Sessions' version of events, it was Comey's job, not Trump's, to make sure that their conversations did not stray into active investigations. His recusal on Russia-related matters wasn't the major problem.
It comes as political intrigue pulses through the United States capital following explosive testimony by Comey before the same panel last week, and as Trump has expressed frustrations with Sessions, one of his earliest high-profile campaign backers.
"I'm not claiming executive privilege, because that's the President's power", Sessions told Sen.
The tactic - combined with the earlier testimony of high-ranking Trump administration officials, who also deemed it inappropriate to divulge conversations with the president - may have given a road map for the White House to keep its secrets without the public-relations blowback of invoking executive privilege.
Scott Fredericksen, a former federal prosecutor and associate independent counsel now in private practice at Foley & Lardner, said Sessions had taken a "legitimate position.to protect the confidentiality of his conversations with the president". "I'm confident of that". So he has to do his best to tame the White House beast while keeping a lid on everything.
Throughout the proceedings, Sessions stuck to his guns and didn't change his story.
It could be because they didn't like seeing one of their former colleagues - Sessions was in the Senate 20 years - under the hot glare of the national spotlight.
On Tuesday, Sessions complained about a "rambling" question from Sen.
"Our committee will want to hear what you are doing to ensure that the Russians - or any other foreign adversaries - can not attack our democratic process like this ever again". The deputy attorney general made clear that only he, not the president, can fire the special counsel and he said he'd there would need to be "good cause" to dismiss Mueller. Jim Risch muttered, "doesn't seem like it". They've gone down lots of other rabbit trails, but not that question.
Some Democrats grew impatient, warning Sessions was stonewalling on vital issues.
Sessions, a senior member of Trump's cabinet and an adviser to his election campaign past year, had a series of tense exchanges with Democrats on the Senate Intelligence Committee during about two and a half hours of testimony as they pressed him to recount discussions with the Republican president.
