The 2020 presidential campaign of Julian Castro, former United States Secretary of Housing and Urban Development, began on January 12, 2019. Castro was the fourth office-holding Democrat to formally announce a campaign in the 2020 U.S. presidential election, following Congressman John Delaney, State Sen. Richard Ojeda, and Congresswoman Tulsi Gabbard.
Castro would have become the first Hispanic president of the United States. Castro would also have been the first president elected from the cabinet since Herbert Hoover.
Castro ended his campaign on January 2, 2020 following low polling numbers. He endorsed Elizabeth Warren for President on January 6.
