Democrat Julian Castro expected to announce 2020 presidential run

Former Secretary of Housing and Urban Development Julian Castro is expected to announce his candidacy for the Democratic presidential nod in his hometown San Antonio, Texas, on Saturday.

Castro would be the only Latino candidate and, at 44, among the youngest of anticipated contenders. In addition to his time in the Obama administration, he previously served as mayor and city council member in San Antonio. He announced his formation an exploratory committee last month and has already visited the early primary states of Iowa, New Hampshire, and Nevada.

Rep. Tulsi Gabbard (D-Hawaii) also announced her candidacy Friday. "I have decided to run and will be making a formal announcement within the next week," Gabbard said. "There are a lot of challenges that are facing the American people that I'm concerned about and that I want to help solve," she continued, listing "the issue of war and peace" as "central to the rest."
