Two senior Democratic politicians have announced they will challenge for the US presidency in 2020.
Julian Castro launched his campaign on Saturday and Tulsi Gabbard said he will make a formal announcement within a week.
Castro should be the only Latin in the race, and Ms. Gabbard is the first Hindu member of Congress.
Both enter what could be a crowded field of Democrats vying to challenge President Donald Trump.
So far only former MP John Delaney has formally launched a campaign, more than a year ago
However, Senator Elizabeth Warren announced last month that she was setting up an exploratory committee to consider a race [1
Mr. Castro made his announcement in his hometown of San Antonio, Texas, where he was mayor from 2009 to 2014.
Aged 44 and a rising star in the party, he was Secretary of Housing under President Barack Obama and was on the list of Hillary Clinton's potential classmates for the 2016 elections.
Having a Mexican grandmother, she used her past to criticize Trump's calls to build a wall for keep migrants away from Latin America.
By launching his offer under the slogan "A nation, a destiny", he said: "We say no to the construction of the wall and yes to the construction of communities".
Said his grandmother would have been amazed by his success and by his brother Joaquin, a member of the United States Congress.
"I have always believed that with great dreams and hard work, everything is possible in this country", he told the crowd
The correspondents say that Castro does not have a widespread name recognition and could struggle to make an impression in a crowded field.
Potential to build a following
It was not long before Julian Castro was considered a high-ranking candidate for the Democratic presidential nomination. He was a well-regarded mayor of San Antonio, made the opening speech of the 2012 National Democratic Convention and took over a position of government in the Obama administration.
Now, however, it may not even end up with the most popular Texan in the race, if the former Congressman (and Democratic heartthrob) Beto O & # 39; Rourke decides to run. And there are other politicians – those who currently hold elective office or, like the former Vice President Joe Biden, with an instant recognition of the name – who are generating more presidential buzz
Although Mr. Castro is not really the star As a newcomer – and, honestly, he was never a particularly compelling speaker – he still has the potential to build a sequel in the coming race. He is a third-generation Mexican-American in an era when Democrats desperately try to engage the growing Latino population in the United States. He is young at a time when many Democrats seek generational change.
As a moderate in a party that moves to the left, however, he has his work cut out for him.
Her launch comes the day after the news emerged that the MP of Hawaii, Mrs Gabbard, will also announce an offer
In an interview with CNN on Saturday night, she says : "There are many challenges facing the American people I'm worried about and wanting to help solve."
A native of American Samoa and a veteran of Iraq, Ms. Gabbard, 37, is seen as a an explicit figure to the left of the party.  In 2017 he caused controversy by announcing he had met Syrian President Bashar al-Assad on a trip to the country.
At the time he said he was ready to meet someone to help end the conflict in Syria, but the opponents described the meeting as shameful.
