"I have never met with or had any conversation with any Russians or any foreign officials concerning any type of interference with any campaign or election in the United States".
Sessions requested an open hearing, though it's not clear what he will and won't address in his televised testimony.
Comey's testimony will form a dramatic sequel to Comey's own appearance before the committee last week, and he will have to tackle several open loops that emerged during that appearance, which twisted the knife in an administration that has struggled to extricate itself from the Russian Federation cloud.
Gen. Xavier Becerra said Tuesday that he supports a proposal for California to adopt a single-payer health plan and believes it will eventually be enacted because consumers will become "fed up" with the current system that he said is unaffordable to many.
The attorney general, a prominent supporter of Donald Trump on the campaign trail, has recused himself from the DOJ Russia investigation.
Democratic senators expressed frustration with Sessions on several occasions.
Democratic Senator Ron Wyden told Sessions, "I believe the American people have had it with stonewalling". He has acknowledged two meetings previous year with Russia's ambassador to the U.S., Sergei Kislyak.
The Justice Department has responded, citing the need to follow "appropriate policies regarding contacts with the White House".
But he denied an alleged third encounter with Kislyak, at an April 27, 2016 reception for Trump at the Mayflower Hotel in Washington.
"Sen. (Al) Franken asked me a rambling question after some six hours of testimony", Sessiona said.
"I did not have any private meetings, nor do I recall any conversations with any Russian officials at the Mayflower Hotel", said Sessions.
Sessions said he was, indeed, "one of the last ones" to leave the White House after a meeting on February 14. He added: "the false attacks, the innuendo, and the leaks, you can be sure, will not intimidate me".
According to Comey, Trump said of Flynn: "He is a good guy".
Sessions is set to testify in an open session of the Senate intelligence committee starting at 2:30 p.m. ET.
As late as Sunday, the Justice Department signaled it expected Sessions' testimony to be closed, but the final decision was up to the committee - with the Justice Department ultimately agreeing to a public hearing.
However, Sessions refused to say whether he ever spoke with Trump about firing Comey.
