Julián Castro, the former mayor of San Antonio and secretary of Housing and Urban Development, formally announced his 2020 presidential campaign Saturday, joining what will be a very crowded field.
Castro, one of the most high-profile Democrats to ever seek the party's presidential nomination, announced his campaign in San Antonio, according to the New York Times.
"When my grandmother got here almost a hundred years ago, I'm sure that 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," Castro said.
Cory Booker (N.J.), Kamala Harris (Calif.), Kirsten Gillibrand (N.Y.), and Bernie Sanders (I-Vt.) are also widely expected to join the race in the coming months.
Castro's identical twin brother, Rep. Joaquín Castro (D-Texas), will serve as campaign chairman, Castro's campaign said.
