Castro has spent years focused on a few core fights. Each is tied to bills actually introduced or votes actually cast.
01
Seeks to restrict arms trafficking to cartelsCastro has sponsored the ARMAS Act in multiple Congresses (HR.6618 in 2023, HR.6736 in 2025) and the Stop Arming Cartels Act (HR.923 in 2025), each directed at limiting the flow of weapons to drug cartels. These bills have drawn substantial cosponsor support across successive legislative sessions.
02
Supports U.S. respect for Mexican sovereigntyCastro sponsored HRES.168, a resolution reaffirming the United States commitment to respecting the sovereignty of Mexico. The resolution has been reintroduced across Congresses, reflecting a sustained legislative focus on the bilateral relationship and the principles governing it.
03
Promotes recognition of Hispanic-Serving InstitutionsCastro has repeatedly sponsored resolutions designating a week in September as National Hispanic-Serving Institutions Week (HRES.682, HRES.969, HRES.1437), each drawing between 50 and 87 cosponsors. These resolutions recognize the role of Hispanic-Serving Institutions in American higher education.
