Sessions's appearance will allow Democrats on the panel to pepper the Justice Department chief about his past statements concerning exchanges with Russian officials during the time he served the Trump campaign last year.

Democrats are particularly interested in his ties to former Trump campaign staffer George Papadopoulos, who pleaded guilty to lying to FBI agents about contacts with Russians. Court documents revealed that Papadopoulos had offered to set up a meeting between Moscow and then-candidate Donald Trump Donald John TrumpUS reimposes UN sanctions on Iran amid increasing tensions Jeff Flake: Republicans 'should hold the same position' on SCOTUS vacancy as 2016 Trump supporters chant 'Fill that seat' at North Carolina rally MORE.

They want to know why Sessions, then a Republican senator from Alabama, failed to previously disclose Papadopoulos's offer to use his contacts and set up a meeting with Russian President Vladimir Putin in March 2016.

Sessions previously told lawmakers that he was "not aware of any of those" contacts between Russian officials and Trump campaign surrogates.

Before his hearing, every Democratic member of the Judiciary panel sent a letter to Sessions about their growing list of questions surrounding Kremlin ties to the Trump campaign.

Reuters first reported that Sessions would appear before a congressional committee on Monday.

Democrats on the Senate Judiciary Committee are also interested in talking to Sessions on this matter.
