President Trump has ordered Immigration and Customs Enforcement (ICE) to “expand efforts to detain and deport” undocumented immigrants in Democratic-run cities.

The big picture: Trump’s order comes as California’s Democratic leaders challenge him in the courts over his deployment of the state National Guard and U.S. Marines to ICE protests in Los Angeles — one of the cities he singled out in Sunday’s Truth Social post.

It builds on the president’s April order directing federal agencies to document “sanctuary cities” that are not complying with his immigration agenda, when the White House said those that failed to do so “may lose federal funding” — prompting a coalition of 20 Democratic attorneys general to file lawsuits against the administration.
