The Trump administration has asked Congress to punish California and other states, cities, and localities with so-called “sanctuary” policies that restrict cooperation with the federal government on matters of illegal immigration by withholding federal grants in a must-pass spending bill that requires action by next week to keep the government running.

A government official on Tuesday told reporters traveling with President Trump to California on Air Force One that the House version of the spending bill already strips out Justice Department and Homeland Security Department grants for California and other sanctuary areas.

“It’s a major threat to national security,” the official said of sanctuary policies according to a pool report. “We are 100 percent committed to challenging sanctuary cities. We will be successful.”

Rep. Mark Meadows (R., N.C.), who chairs the conservative House Freedom Caucus, has pushed the idea of withholding federal grants for California and other sanctuary areas.

“Why should Congress continue pouring taxpayer dollars into cities that defy federal immigrant law?” he tweeted Monday. “That shouldn’t happen in America—a nation of law and order. @POTUS is right—Congress can withhold federal grants in the upcoming omnibus. It’s time to #DefundSanctuaryCities.”

Senate Democrats will likely balk at any effort to include similar language punishing California and other municipalities in the omnibus appropriations bill. Still, after Democrats lost the government shutdown war in January because of a standoff over a deal to permanently resolve the legal status of “dreamer” immigrants, they could be more reluctant to draw any firm lines in the sand.

Senate Minority Leader Chuck Schumer (D., N.Y.) on Tuesday said Democrats do not want to fund Trump’s border wall in the omnibus spending bill but did not rule out providing money for other Trump immigration priorities.
