Tulsi Gabbard, the former Democratic presidential candidate who wanted to take on Donald Trump in 2020, made a stunning about-face on Monday by wholeheartedly endorsing the former president.

Gabbard left her safe Hawaii House district in 2019 to join the crowded 2020 Democratic presidential field. After dropping out of the race, she endorsed Joe Biden as the best man to “heal the divisions that have torn our country apart.”

But on Monday, she spoke at a National Guard Association meeting in Detroit, Michigan, where Trump also spoke, and urged the country to vote for him. “I am committed to doing everything I can to return President Trump to the White House,” she said.

Gabbard served in the Army National Guard in Afghanistan, where she was decorated for her service. She is now an officer in the Army Reserve and used her military credentials as part of her justification for supporting Trump.

“I know what I mean when I share with you that President Trump understands the grave responsibility a president and commander in chief bears for each of our lives,” she said.

“He holds us in his heart in the decisions he makes,” she added. “We saw this in his first term as president, when he not only did not start new wars, but he took action to de-escalate and prevent wars. The same cannot be said about Kamala Harris. In fact, the opposite is true.”

Gabbard’s political transformation has taken her from the antiwar wing of the Democratic Party to the inner MAGA circle. She helped Trump prepare for his debate with Vice President (and current presidential candidate) Kamala Harris, after she delivered a critical blow to Harris during a July 2019 Democratic debate, when they clashed over the then-California senator’s record as a prosecutor.

She has also touted herself as a potential running mate for Trump, saying just before he was convicted of 34 felony counts of keeping false records that she would be “honored” to be on the list.

Her embrace of the conservative movement has led to her being signed to a Fox News staff position and speaking at the Conservative Political Action Committee’s CPAC meeting; her book For the love of country: leave the Democratic Party behinduses the term “Democrat” instead of “Democratic” as a dig at the party. She was once vice chair of the Democratic National Committee.

The 43-year-old lives with Abraham Williams, her second husband, in California and Texas.

The timing of her show of support was no coincidence. Gabbard, a member of the Hawaii National Guard, had earlier accompanied Trump to Arlington National Cemetery in Virginia to lay a wreath on the third anniversary of the deaths of 13 U.S. service members at Kabul Airport’s Abbey Gate during the chaotic withdrawal from Afghanistan.

Trump’s campaign is hoping to use the bloody exodus from Afghanistan as a line of attack on Harris, who has said she was the last person in the room when President Joe Biden ordered a full withdrawal from Afghanistan. Trump himself brokered the deal that led to the withdrawal and had planned to host Taliban members at Camp David on Sept. 11, 2019, to finalize it.
