Castro has an identical twin brother, Julian Castro, who was mayor of San Antonio, U.S. Housing Secretary, and a 2020 presidential candidate — people mix them up constantly.
Joaquin Castro is a San Antonio native and Harvard-trained lawyer who has represented Texas' 20th Congressional District since 2013. He chairs the Congressional Hispanic Caucus and sits on the House Foreign Affairs and Intelligence Committees. He's running for re-election, focused on healthcare costs, protecting Dreamers, and fighting the 2025 Texas congressional redistricting that cut into his district.

Castro called Texas's 2025 mid-decade congressional map an 'illegal power grab' that hurts Latino and Black voters and pledged to fight it, and he co-sponsored the Voting Rights Advancement Act. [Castro House press releases]
