Texas Rep. Joaquin Castro was elected Friday as the next chair of the Congressional Hispanic Caucus, which will begin the next Congress with its largest membership since the group’s founding.

The CHC had 31 members this Congress and will grow to 39 members next year — two senators and 37 House members.

The caucus picked its new leadership team Friday, with several current leaders moving to higher positions.

Castro will be moving from first vice chair to chairman. Arizona Rep. Ruben Gallego, the current second vice chair, will take over as first vice chair. New York Rep. Adriano Espaillat will ascend from freshman representative to whip.

California Rep. Nanette Barragán will serve as a new member of CHC leadership as second vice chair. Texas Rep.-elect Veronica Escobar will also join the CHC leadership as the freshman representative.
