The U.S. Senate voted on Monday to advance the nomination of former Representative Tulsi Gabbard to be director of national intelligence, continuing President Donald Trump's successful push to confirm even his most at-risk nominees for administration positions.

The test vote indicated that despite early reservations even among some Republicans, the former Democratic congresswoman had the necessary support to be confirmed in a vote expected by Wednesday.

Gabbard is now on track to be confirmed as the director of national intelligence, despite some concerns from members of both parties.
