President Donald Trump’s takeover of California’s National Guard to fend off immigration protesters in Los Angeles, halted briefly by a federal judge, is starting to climb up the judicial ladder, with a federal appeals court hearing scheduled Tuesday.

U.S. President Donald Trump can keep his deployment of National Guard troops in Los Angeles, according to a court ruling, as protests against immigration raids look set to enter their second week in the strongest backlash since his return to power in January.

The appeals court issued its pause just hours after Judge Charles Breyer wrote that Trump’s “actions were illegal." The 9th Circuit Court of Appeals will hear the case on June 17.
