The Democratic National Committee is calling on Sen. Jeff Sessions, R-Ala., to recuse himself from his nomination for U.S. attorney general following a report that he has withheld information that the Senate will need to decide on whether to confirm him.

The report, produced by progressive groups, accused Sessions of neglecting to provide “major details from his years as U.S. attorney for the Southern District of Alabama, from 1981 to 1993; as attorney general of Alabama, from 1995 to 1997; and as a first-term U.S. senator, from 1997 to 2002,” according to the Huffington Post.
