After promising to hold ICE agents accountable at an event on Tuesday, Philly District Attorney Larry Krasner is now joining a coalition of prosecutors around the country to ensure federal agents are prosecuted for any violation of state laws.

And, while going so far as to call ICE agents “wannabe Nazis,” Krasner promised that any federal agent who violates those rights or breaks any state law would be held accountable.

Even, he said, if law enforcement officials needed to wait until Donald Trump was out of office to do so.

“If we have to hunt you down the way they hunted down Nazis for decades, we will find your identities. We will find you. We will achieve justice,” Krasner said.
