A federal appeals court on Thursday cleared the way for President Trump to keep using the National Guard to respond to immigration protests in Los Angeles, declaring that a judge in San Francisco erred last week when he ordered Mr. Trump to return control of the troops to Gov. Gavin Newsom of California.

A federal appeals court will hear arguments regarding California's challenge to Trump's mobilization of the troops.

A panel rejected a lower-court’s finding that it was likely illegal for President Trump to use state troops to protect immigration agents from protests.
