The Senate Intelligence Committee will vote Tuesday on whether to advance Gabbard's nomination, the New York Times reported.

A source with knowledge of the proceedings told ABC News that newly confirmed CIA Director John Ratcliffe, former NSA adviser Robert O'Brien and former Sen. Richard Burr, a former Senate Intelligence Committee chairman, have been making calls to senators on Gabbard's behalf. Gabbard has also talked to senators since her hearing, a source said.

Sen. Todd Young revealed his plan to vote for Tulsi Gabbard in committee, boosting her odds of advancing to the floor and ultimately being confirmed.
