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

Young said he sought commitments from Gabbard to "advance our national security." Young had been under pressure to support Trump's pick.

The Senate Intelligence Committee will vote on her nomination in a closed session, according to a committee aide. Republicans have a one-seat majority on the panel, meaning Gabbard cannot afford to lose a single GOP vote if all members are present.
