PHILADELPHIA (AP) — Cities large and small were preparing for major demonstrations Saturday across the U.S. against President Donald Trump, as officials urge calm, National Guard troops mobilize and Trump attends a military parade in Washington to mark the Army’s 250th anniversary.

Judge Charles Breyer ordered the administration to return control of the National Guard to the California governor, but an appeals court stayed the extraordinary decision Thursday night.

“He is not a monarch. He is not a king, and he should stop acting like one,” Newsom told reporters outside the federal courthouse after an emergency hearing in downtown San Francisco.

Homeland Security Secretary Kristi Noem pledged to carry on with the Trump administration’s immigration crackdown despite waves of unrest across the U.S.

A federal court will hear arguments this afternoon on California Gov. Gavin Newsom’s emergency motion seeking to block troops deployed by President Donald Trump to Los Angeles from enforcing immigration and local law.

On Tuesday, the X page for U.S. Immigration and Customs Enforcement (ICE) posted photos of California National Guardsmen on the scene of a detention being carried out by an ICE agent with the caption "Photos from today's ICE Los Angeles immigration enforcement operation."

The president thinks California Governor Gavin Newsom should be thanking him, even though he didn’t do anything.

Their clash over Trump’s deployment of military forces for anti-ICE protests in Los Angeles is far from the first time the two leaders have butted heads.
