Time to rumble.

(The Hill) — The House will vote before the Senate on the debt-ceiling agreement, a GOP leadership aide said Monday.

The vote is expected Monday evening or night, but a time has not been set. The GOP aide cautioned that the schedule in the House is “very fluid,” but said the vote would occur “hopefully tonight.”

The House Rules Committee has scheduled a hearing for 1:10 p.m. to send the bill to the floor.

Leaders of both parties are urgently trying to secure enough votes to pass the package. The White House dispatched Vice President Biden to the Capitol to sell the deal to House and Senate Democrats, while Speaker John Boehner (R-Ohio) will brief House Republicans on the deal for the second day in a row.

Biden, who worked closely with Senate GOP leader Mitch McConnell (Ky.) on the agreement, on Monday told reporters he thinks the deal will pass. McConnell said he is “very optimistic” it would be approved. McConnell

House Minority Leader Nancy Pelosi (D-Calif.) is also meeting with her caucus Monday afternoon to discuss the deal. She emphasized positive aspects of the deal before the meeting, but did not pick a side.
