Castro has chucked in his hat into the ring
Texas Democrat Julian Castro launches 2020 campaign
Texas Democrat Julian Castro, a former San Antonio mayor who went on to be the top US housing official, formally announced his White House bid on Saturday, making him the first Hispanic in what looks to be a crowded field of candidates vying to challenge President Donald Trump in the November 2020 election.
Mr Castro, 44, the grandson of a Mexican immigrant who would be the first Hispanic elected president, served as secretary of Housing and Urban Development under former President Barack Obama and has long been viewed as a rising star in the party. He will seek to position himself as a political outsider with liberal credentials.
"When my grandmother got here almost a hundred years ago, I'm sure she never could have imagined that just two generations later, one of her grandsons would be serving as a member of the United States Congress and the other would be standing with you here today to say these words: I am a candidate for President of the United States of America," Mr Castro said in a statement announcing his campaign.
