Dozens of mayors from across the Los Angeles region joined forces Wednesday, calling on the Trump administration to halt intensified immigration raids that have stoked fear in their communities and fueled nationwide protests.

Their plea, however, appeared to fall on deaf ears.

Roughly 500 National Guard troops assigned to support Los Angeles protests have also been trained to assist in immigration enforcement operations, according to the commanding officer, Maj. Gen. Scott Sherman.

While some of those troops have already participated in such missions, Sherman said it remains unclear whether those deployments will continue once the demonstrations subside.

“We are expecting a ramp-up,” Sherman said, acknowledging broader discussions around protests sweeping the country. “I’m focused on what’s happening here in L.A., but we’re definitely concerned.”
