U.S. Rep. Tulsi Gabbard, known for bucking the party establishment and criticizing U.S. foreign policy in the Middle East, formally launched her campaign for president with a video posted online Thursday.

Gabbard joins a growing field of Democrats seeking their party’s nomination. U.S. Housing Secretary Julian Castro recently announced a bid, and Sens. Elizabeth Warren of Massachusetts, Kirsten Gillibrand of New York and Kamala Harris of California say they are running.

“We have people in positions of power who are not thinking about the well-being of the people and our planet,” Gabbard said in the video. “Where is that conversation about the needs of our people?”

Gabbard, 37, has represented Honolulu’s suburbs and rural Hawaii in the U.S. House since 2013. She is a combat veteran who served in Iraq and Kuwait with the Hawaii National Guard.

She was an early, vocal supporter of Vermont Sen. Bernie Sanders during the last presidential campaign, which has made her popular with progressive Democrats.

Gabbard indicated in an interview with CNN earlier this month that she would be a candidate. She said she would follow it up with a formal launch, which occurred Thursday.

Critics have focused on her past advocacy against same-sex marriage.

In one example she spoke at a news conference in 2004 when she was a state representative about federal judges “tearing apart our U.S. Constitution in order to force same-sex marriage down the throats of the people of Hawaii and America.”

She appeared on behalf of Alliance for Traditional Marriage and Values, an organization founded by her father to lobby against same-sex marriage.

Gabbard released a nearly four-minute-long video statement on YouTube last week explaining how she grew up in a socially conservative household but has since formed her own opinions shaped by her life experiences. She apologized for her past statements and the harm they caused.

“I look forward to being able to share more of my story and experiences growing up — not as an excuse, but in the hopes that it may inspire others to truly live aloha, to love and care for others,” she said.

Gabbard has said she’s motivated by U.S. foreign policy that has led the country into military conflict in Iraq, Libya and Syria.

She said the actions in the Middle East have destabilized the region, made the U.S. less safe and cost thousands of American lives. At the same time, terrorist groups like al-Qaida and the Islamic State group are stronger than before the Sept. 11, 2001, terrorist attacks, she said.

In her new video Thursday, she said all Americans have paid the price for what she called “interventionist, regime-change wars.”

“We have spent trillions of your taxpayer dollars to pay for these wars, taking those dollars away from our communities and our people who need them right here at home,” she said.

Gabbard stands out from other candidates in many ways. She’s the first Hindu to be elected to Congress and is the first born in American Samoa. She’s also an avid surfer.

She’s among the youngest, along with Pete Buttigieg, the 37-year-old mayor of South Bend, Ind., seeking the presidency.
