Gonzalez was one of three Texas representatives who endorsed the former HUD secretary, along with Castro’s twin brother, Rep. Joaquin Castro, and Rep. Colin Allred. Gonzalez announced his endorsement for Castro in March, saying at the time: “I know firsthand his passion for expanding opportunity for the Latino community, people of color, and historically disenfranchised communities, as well as his unparalleled dedication to building a bench of dynamic Democratic candidates in Texas and nationally.”

Gonzalez announced his switch to CNN’s Jake Tapper on Sunday morning saying: “I think at this point in time we need to narrow the field and unite as Democrats to defeat Trump in November 2020. And that is why I believe I’m moving my support to Vice President Joe Biden.”
