SAN ANTONIO, Texas/WASHINGTON (Reuters) - Texas Democrat Julian Castro, a former San Antonio mayor and top U.S. housing official, formally launched his White House bid on Saturday, entering as a dark horse candidate in a likely crowded field vying to challenge President Donald Trump in the November 2020 election.
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.
