UPDATE 12:11 p.m. EST: Sessions refuted allegations of racial animosity that prevented him from earning a federal judge position 30 years ago. He said the accusations were part of a "caricature."
In 1986, he was accused of calling a black lawyer "boy" and calling the ACLU and NAACP "un-American."
He also said he would not support a ban on Muslims entering the United States, which Donald Trump has repeatedly called for.
UPDATE 11:15 a.m. EST: If confirmed as Attorney General, Sen. Sessions pledged to recuse himself from any Hillary Clinton issues raised during the 2016 election. Sessions told lawmakers because of comments he has made, "I believe the proper thing for me to do would be for me to recuse myself."
With President-elect Donald Trump's inauguration just days away, confirmation hearings for his cabinet picks are set to begin.
On Tuesday, attorney general pick Jeff Sessions and Secretary of Homeland Security pick John Kelly are up to bat. Sessions' hearing starts at 9:30 a.m. Eastern, and Kelly's is at 3:30 p.m. Eastern Sessions is expected to be more controversial. Sen. Cory Booker, a Democrat from New Jersey, will testify against him. No Senator has ever testified against another Senator's cabinet hearing, CNN reports.
Can Sessions be stopped?
It's doubtful. He has strong support among Republicans. He's been consistently conservative. But Democrats have blasted his past racist comments and expressed concerns that he would leave LGBT people, minorities and immigrants legally vulnerable .
His hearing will take two days, and witnesses will speak up for and against his character on Wednesday.
Dems trying to delay
Senate Democrats are demanding for the hearings to be delayed until Trump's nominees are fully vetted by the Office of Congressional Ethics (OGE).
The director of the OGE sent Democratic leaders a letter raising concerns because they have yet to receive basic financial disclosure records from several of the nominees, including tax returns.
Senate Majority leader Mitch McConnell said all nominees would be fully vetted.
