The Trump administration has vowed to overturn a federal judge’s decision to block President Trump’s executive order cutting off federal funds to sanctuary cities, counties, and states.

A federal judge in Northern California determined Monday that Trump cannot place new conditions on spending Congress has approved. The judge’s ruling responded to lawsuits brought by two California counties, San Francisco and Santa Clara, taking exception to Trump’s threat to cut off federal grants to localities that limit law enforcement’s cooperation with U.S. immigration authorities.

The Justice Department late Monday countered that cities, counties, and states do not have the ability to flout federal law and continue receiving federal money without any repercussions.

“The District Court exceeded its authority today when it barred the president from instructing his cabinet members to enforce existing law,” said Justice Department spokeswoman Devin O’Malley. “The Justice Department will vindicate the president’s lawful authority to direct the executive branch.”
