President Donald Trump signed an executive order on Monday aimed at identifying and cutting off federal funds to sanctuary cities

Last week, a federal judge blocked the administration's latest effort to withhold funding from 16 jurisdictions, including San Francisco, Portland, Seattle, Minneapolis, St. Paul and New Haven.

"Here we are again," wrote U.S. District Judge William Orrick in San Francisco, who found that the Trump administration's actions were likely unconstitutional and granted a preliminary injunction.

"The threat to withhold funding causes them irreparable injury in the form of budgetary uncertainty, deprivation of constitutional rights, and undermining trust between the Cities and Counties and the communities they serve," Orrick wrote.
