The confrontation escalated on Monday as new protests occurred and Defense Secretary Pete Hegseth announced — on X — that he was mobilizing 700 Marines from a base near Los Angeles to guard federal buildings. They are expected to join 2,000 members of the California National Guard whom Mr. Trump ordered deployed without the authorization of the state’s governor, Gavin Newsom, who normally has command of the troops.
The latest deployments prompted a new wave of misleading images to spread — some purporting to show Marines and the military service’s weapons in action. One was a still from “Blue Thunder,” a 1983 action-thriller about a conspiracy to deprive residents of Los Angeles of their civil rights. It features a climactic dogfight over the city’s downtown.
Darren L. Linvill, a researcher at Clemson University’s Media Forensics Hub, said conservatives online were “building up the riots in a performative way” to help bolster Mr. Trump’s claims that Los Angeles had been taken over by “violent, insurrectionist mobs.”
Dr. Linvill said the posts were also “a bit self-fulfilling.” “As they direct attention to it,” he said, “more protesters will show up.”
James Woods, the actor who has become known for spreading conspiracy theories, used his account on X to rail against the state’s elected officials, especially Mr. Newsom, a Democrat. He also reposted a fabricated quote, attributed to former President Barack Obama, discussing a secret plot to impose socialism on the country, as well as a video of burning police cars that was from 2020.,
