The Marines began nonlethal training while preparing to deploy to Los Angeles to supplement National Guardsmen there.

Defense Secretary Pete Hegseth stood by the Trump administration's National Guard federalization and U.S. Marines deployment to the Los Angeles anti-ICE riots.

The spokesperson told CNN the Marines "have not completed [Standing Rules for the Use of Force] and nonlethal weapons training."

“Constitutionally, as a nation, we do not want to use active duty troops, deploy them against American citizens and others residing in our country. Because the impact is so negative. It makes it appear that the United States of America is a battleground,” Barthel said.
