Senate Democrats are planning another all nighter, this time to protest Alabama Sen. Jeff Sessions' nomination to be the next U.S. Attorney General.

Democratic sources told The Hill lawmakers plan to talk from Tuesday night into Wednesday ahead of the vote on Sessions. On Tuesday, the Senate voted to proceed with Sessions' nomination, starting the clock on a 30-hour period in which debate can take place.

Senate Democrats did the same thing the previous night to protest the nomination of Betsy DeVos to lead the Department of Education. DeVos' nomination passed Tuesday but only after tie-breaking vote from Vice President Mike Pence in his role as Senate leader.

During earlier hearings, Democrats had criticized Sessions for his handling of civil rights cases while he was a federal prosecutor and for alleged racially insensitive remarks. Sessions has denied the allegations.

Sessions is expected to be confirmed Wednesday with the GOP holding the majority in the Senate and all Republicans in the Upper Chamber, as well as West Virginia Democrat Joe Manchin, indicating they support for his nomination.

Sessions was the first Senator to endorse Donald Trump's bid for the presidency and has been one of his strongest supporters.
