Twenty-eight of California’s congressional representatives are throwing their weight behind state legislation that would make it harder to deport immigrants who are in the country illegally. The representatives — all Democrats, including House Minority Leader Nancy Pelosi of San Francisco — sent a letter to Gov. Jerry Brown urging him to sign the bill if it reaches his desk. The bill, known as the Trust Act, "establishes a bright line standard between local law enforcement and federal immigration enforcement" and would "continue California’s proud tradition of being a leader on smart and sensible policies," the letter says. The representatives said unnecessary deportations have "reduced the willingness of immigrant and non-immigrant crime victims and witnesses to cooperate with local law enforcement, and consequently has diminished public safety."
