"I think it’s most important for us, as we look at our choices as to who our next commander in chief will be, is to recognize the necessity to have a commander in chief who has foresight, who exercises good judgment, who looks beyond the consequences, looks at the consequences of the actions they're looking to take, before they take those actions, so we don't continue to find ourselves in these failures that have resulted in chaos in the Middle East and so much loss of life," Gabbard said.

The Hawaii Democrat's tenure at the DNC has not been without controversy. In October, she complained she was “disinvited” from a debate after she urged the party to hold more debates. Sanders later offered her a seat with his campaign.

Gabbard has been described as one of the Democratic Party's next rising stars. Still in her first term, she is the first Hindu elected to Congress and the first person born in American Samoa. She is also one of only two female combat veterans elected to Congress.

"Today I accepted Congresswoman Tulsi Gabbard's resignation as a Vice-Chair of the DNC. The Democratic National Committee is grateful for her service,” DNC Chairwoman Debbie Wasserman Schultz said in a statement, calling Gabbard a “role model.”

“I look forward to continuing to work alongside her when our Party unites behind whoever emerges as our nominee.”
