Sen. Susan Collins (R-ME) announced she will vote to confirm President Donald Trump’s pick to lead the U.S. intelligence community, Tulsi Gabbard, raising the prospects that the former Democratic congresswoman will be able to advance out of the critical Senate intelligence panel.

Gabbard’s nomination will be considered voted on behind closed doors on Tuesday by the Senate Intelligence panel, where her nomination could come down to one vote. The committee is split 9-8 in favor of Republicans, meaning if all panel Democrats oppose Gabbard, as is expected, a single GOP flip could prevent her nomination from reaching the floor.
