A federal judge blocked President Trump’s planned freeze on federal grants and loans on Tuesday evening, just before it was supposed to go into effect.

The freeze is part of an effort to curb trillions of dollars in federal spending. U.S. District Judge Loren L. AliKhan’s administrative stay has blocked the Trump administration’s measure until at least Monday, in response to an appeal filed by a network of nonprofit groups.

AliKhan’s decision comes after Office of Management and Budget director Matthew Vaeth ordered agencies to “temporarily pause all activities related to obligation or disbursement of all Federal financial assistance” and “identify and review all Federal financial assistance programs and supporting activities consistent with the President’s policies and requirements.”

During her first White House press briefing on Tuesday, press secretary Karoline Leavitt said that the directive was the Trump administration’s effort to be “good stewards for tax dollars.”

“I think this is a very reasonable measure,” she said, adding that the freeze would allow the government time to cut back diversity, equity, and inclusion initiatives that Trump opposes. Programs “that [provide] direct benefits to individuals,” including the Supplemental Nutrition Assistance Program (SNAP), and Medicare and Social Security would not be affected, Leavitt added.
