In a disheartening development for immigrants’ rights advocates, California Governor Jerry Brown vetoed the TRUST Act on Sunday just hours before it was scheduled to take effect. The measure, which was intended to minimize the humanitarian impact of the federal Secure Communities program, would have largely prohibited state and local jails from detaining suspects on behalf of federal immigration authorities. Importantly, however, Gov. Brown rejected a central argument of the bill’s critics in his veto message and pledged to work with the California legislature to fix what he described as the flaws in the bill.
