At least three Republican senators on the panel that will decide whether to advance Tulsi Gabbard’s nomination as Director of National Intelligence have not said how they plan to vote, according to Politico—leaving open the possibility she could be the first of President Donald Trump’s nominees to be rejected.

Ahead of a Senate Intelligence Committee hearing Thursday, the fate of Gabbard’s nomination rests in the hands of a small handful of undecided GOP senators: Maine’s Susan Collins, Indiana’s Todd Young, Kentucky’s Mitch McConnell and Utah’s John Curtis.

Tulsi Gabbard says she now supports surveillance she once tried to end. The issue could decide whether she's confirmed as director of national intelligence.
