The list of Democrats eyeing the White House may be getting longer: U.S. Rep. Tulsi Gabbard, D-Hawaii, is said to be "seriously considering" a 2020 presidential bid, according to reports.

Gabbard, the first Hindu-American elected to Congress, paid a visit to New Hampshire last week, a state that has held the nation's first presidential primary every four years, the Hawaii Civil Beat reported.

“As I have throughout my life in making the different decisions that I’ve made, I am thinking about how I can best be of service to the people of this country,” Gabbard said, according to the paper.

Gabbard, who was recently re-elected to a fourth term representing the Hawaii's 2nd Congressional District, said she did not have any timetable for deciding on a White House bid, the Honolulu Star-Advertiser reported.

She was a major in the Hawaii Army National Guard and served two tours of duty in the Middle East.

Gabbard, 37, strongly supports the House of Representatives' "Medicare for all" bill and getting big money out of politics, the Star-Advertiser reported.

Last month, Gabbard made headlines for referring to President Trump as "Saudi Arabia's b----," after the president argued for the importance of a strong U.S-Saudi relationship amid calls for him to take a tougher stance on the kingdom in response to the killing of writer Jamal Khashoggi.

But Gabbard has herself faced criticism for meeting with Syrian President Bashar al-Assad in 2017 in Damascus.

Gabbard also faced criticism during her re-election campaign for shying away from debating her primary opponent, continuing a pattern that has developed since she was first elected to Congress.

Ironically, Gabbard resigned from her position with the Democratic National Committee in 2016 because she believed the party hadn't scheduled enough debates among its presidential candidates that year.

Also said to be considering a 2020 presidential run is Texas Democrat Julian Castro, former President Obama's housing chief.

Castro, 44, launched a 2020 presidential exploratory committee this week.

“Americans are ready to climb out of this darkness. We’re ready to keep our promises. And we’re not going to wait. We’re going to work,” Castro, 44, said in a video. “That’s why I’m exploring a candidacy for president of the United States in 2020.”

An exploratory committee usually is a formality before a candidate launches a presidential campaign. It legally allows potential candidates to begin raising money.

The former San Antonio mayor said his official decision will be announced on Jan. 12. Sens. Elizabeth Warren of Massachusetts, Cory Booker of New Jersey and Kirsten Gillibrand of New York, along with former Vice President Joe Biden and Colorado Gov. John Hickenlooper, are also potential presidential candidates.

Another well-funded set, including Vermont Sen. Bernie Sanders, Texas Rep. Beto O'Rourke, Bloomberg and Steyer, believe they can afford to wait slightly longer to announce their intentions given their fundraising prowess.

Previously mulling a 2020 presidential bid was firebrand attorney Michael Avenatti, politically famous for representing porn star Stormy Daniels.

He announced early this month that he will not run for the White House in 2020, citing family concerns for his decision.

“After consultation with my family and at their request, I have decided not to seek the Presidency of the United States in 2020. I do not make this decision lightly—I make it out of respect for my family. But for their concerns, I would run,” Avenatti said in a statement posted on Twitter.

Former Massachusetts Gov. Deval Patrick also bowed out of the 2020 presidential contest last week, citing the "cruelty of our elections process" and the effect it would have on his loved ones.

"After a lot of conversation, reflection and prayer, I've decided that a 2020 campaign for president is not for me," Patrick, 62, posted on his Facebook page.
