It will be the first sworn public testimony from Sessions, a longtime former senator, since he was nominated by President Donald Trump and confirmed as the nation's top law enforcement officer in February.
New questions about Sessions were raised last week, after former FBI Director James Comey said that he and other leaders at the agency had expected Sessions to recuse himself weeks before he did - and that the reasons behind that thinking are classified.
People familiar with Comey's testimony in a second, closed hearing on Thursday, said the former director told the intelligence committee that Sessions may have had a third, undisclosed interaction with Russia's ambassador to the United States, Sergey Kislyak. Was he aware the president had made a decision to fire Comey before seeing that memo - and did he ask the DOJ to prepare that memo for him?
The president sacked Comey in early May.
As these investigations remain ongoing, no substantive evidence exists that shows the Trump campaign worked with Moscow.
But Sessions, who recommended in a signed memo that Comey be fired, may end up claiming executive privilege as a means of limiting the breadth of his testimony.
The White House on Monday suggested Sessions could invoke executive privilege during his testimony depending on "the scope of the questions".
"To get to a hypothetical at this point would be premature", he added.

Democratic senators will no doubt push him on this explanation, particularly as senators Patrick Leahy and Al Franken requested an FBI investigation into whether or not Mr. Sessions committed perjury in his confirmation hearings when he denied having any contacts with Russians during the campaign.
In March, Sessions recused himself from any investigations into Russia's actions in the 2016 campaign. Sessions is expected to face sharp questioning from his former Senate colleagues about his role in the investigation into contacts between Trump campaign associates and Russian Federation during the 2016 election. "Let's find out under oath what it was". "Sessions actually offered to resign, even though his friends say he doesn't want to leave, but Trump has refused to accept that resignation".
Comey told the intelligence committee in a closed session that Sessions may have had a third, undisclosed interaction with Russia's ambassador to the USA, according to people familiar with the briefing.
Comey recalled that he felt "something big" was about to happen, and "my sense was the attorney general knew he shouldn't be leaving".
Sessions was nominated to be attorney general in the middle of November, before Kushner reportedly attempted to set up a back channel with Russian officials.
Comey described the Oval Office meeting, before his one-on-one with Trump, as "a scheduled counterterrorism briefing". Did Sessions remember that?
Comey said last week that the bureau had information about Sessions - before he recused himself from overseeing the investigation into Russian meddling in the 2016 election - that would have made it "problematic" for him to be involved in the probe. While Comey did not run to tell Sessions of his concerns over what the President supposedly said about the investigation of Michael Flynn, Comey did say he asked Sessions to shield him from Mr. Trump, anxious by the President's phone calls and questions.
"I hope you can see your way clear to letting this go, to letting Flynn go", Comey quoted Trump as saying.
What Sessions will and won't choose to answer "is up to him", CNN's senior legal analyst Jeffrey Toobin told Wolf Blitzer on "The Situation Room" on Monday.
