Tulsi Gabbard, a prominent congressional supporter for Bernie Sanders' campaign, says she will now back Democratic nominee Hillary Clinton.

"Given the remaining choices, like Bernie Sanders, I will be casting my vote for Hillary Clinton," the Hawaii congresswoman said in an interview with the Honolulu Star-Advertiser published Thursday.

"Moving forward, as a veteran and someone who knows firsthand the cost of war, I am going to continue to push for an end to counterproductive interventionist wars and lead our country toward a path toward peace," she added.

Gabbard resigned from her post as vice chair of the Democratic National Committee after a feud that began when she criticized its then-chairwoman, Debbie Wasserman Schultz, for sanctioning too few debates in order to tip the scales in favor of Clinton, the front-runner. Afterwards, she became one of a handful of Democrats in Congress to get behind Sanders' long-shot campaign.

She nominated Sanders for president during her speech at last week's Democratic convention in Philadelphia.
