The deputy director of the FBI said “multiple arrests” have been made in both Los Angeles and New York after protests broke out in both cities due to immigration enforcement.

“We are not intimidated or apprehensive,” FBI Deputy Director Dan Bongino said on Sunday morning in a post on X. “Illegal immigration operations will continue, and anyone using violence to obstruct or impede these operations will be investigated and prosecuted.”

Bongino added, “We are not stopping or slowing down.”

Bongino said many of those arrested “will face federal charges, along with local and state charges.”

“It will not end well for you if you choose violence. Choose wisely,” Bongino said.

In a post on X Saturday night, FBI Director Kash Patel warned: “Hit a cop, you’re going to jail… doesn’t matter where you came from, how you got here, or what movement speaks to you. If the local police force won’t back our men and women on the thin blue line, we @FBI will.”

“Violence and intimidation against federal law enforcement will be prosecuted to the fullest extent of the law,” according to a Sunday-morning post on X by the Department of Homeland Security. “These violent rioters are fighting against LAW and ORDER,” the post added.
