California Leads New Lawsuit Over Trump Rule Targeting Poor Immigrants

California and three other states on Friday filed the latest court challenge to new Trump administration rules blocking green cards for many immigrants who use public assistance including Medicaid, food stamps and housing vouchers.

Nearly half of Americans would be considered a burden if the same standards were applied to U.S. citizens, said California Attorney General Xavier Becerra.

"This Trump rule weaponizes nutrition, health care and housing," Becerra said, by potentially blocking legal immigrants from becoming citizens, "if your child participates in something as basic as your neighborhood school lunch or nutrition program."

The lawsuit he filed in U.S. District Court in San Francisco follows others this week including those by Washington and 12 other states, and by San Francisco and Santa Clara counties. Joining California are Maine, Oregon and Pennsylvania, as well as the District of Columbia.

Thirteen immigrant advocacy and legal groups led by La Clínica de la Raza filed a separate lawsuit Friday in the same court, arguing the regulation was motivated by racial bias.

The lawsuits all contest one of President Trump's most aggressive moves to restrict legal immigration. A spokesman for the White House declined comment while U.S. Citizenship and Immigration Services did not respond to a request for comment.

The new rules set to take effect in October would broaden a range of programs that can disqualify immigrants from legal status if they are deemed to be a burden to the United States — what's known as a "public charge."

Becerra, a Democrat, said working families across the country rely on similar safety net programs. The impact is particularly great in California, which has more than 10 million immigrants.

"This Trump rule disproportionately impacts Californians, that’s obvious," he said. "Almost half of all California children have at least one immigrant parent."

His lawsuit argues that the rule creates unnecessary new obstacles for immigrants who want to legally live in the United States. It also discourages them from using health, nutrition, housing and other programs for fear it will erode their chances of being granted lawful status.

Becerra's mother was born in Mexico, coming to the U.S. after marrying his father, and he said she likely would have been affected by the policy. However, the rules don't apply to U.S. citizens, even if the citizen is related to an immigrant who is affected.

Many immigrants are ineligible for public benefits because of their status, and an Associated Press analysis found low-income immigrants use Medicaid, food aid, cash assistance and Supplemental Security Income, or SSI, at a lower rate than comparable low-income native-born adults.

Those who work with immigrants say the rule, which doesn't go into effect until October, is already having a negative impact. California counties administer the food stamp program and Medi-Cal in the state.

"The data are hard to tease out, but we have heard, for about two years now, every time there's been coverage of a possible rule coming forward, people will call and they will say please remove me from the rolls. Or please withdraw that application that I had filed," said Cathy Senderling-McDonald, deputy executive director of the County Welfare Directors Association of California.

Trump's attempts to thwart illegal immigration have drawn the most attention, but the latest announcement Monday affects people who entered the United States legally and are seeking permanent status.

"We want to see people coming to this country who are self-sufficient," said Ken Cuccinelli, the acting director of Citizenship and Immigration Services.
