A Massachusetts man faces up to five years in prison for offering on Twitter to pay $500 to anybody who kills a U.S. Immigration and Customs Enforcement (ICE) agent.

The U.S. Attorney's Office for the District of Massachusetts said that Brandon Ziobrowski, 33, from Cambridge, Mass., was charged with one count of use of interstate and foreign commerce to transmit a threat and injure another person for the alleged Twitter post earlier this year.

On July 2, the 33-year-old allegedly tweeted: “I am broke but will scrounge and literally give $500 to anyone who kills ICE agent. @me seriously who else can pledge get in on this lets make this work.”

Federal officials said Ziobrowski in March started tweeting threatening messages against federal agents that work for ICE.

On "Fox & Friends," former acting director of ICE Thomas Homan said it's common for ICE agents to be threatened, but those threats will not have the desired effect.

"ICE will not be bullied into not doing their job. That's not going to work," Homan said.

Homan, who retired one month ago, said ICE is under fire from the far-left, which wants to abolish the agency and establish open borders.

"I'm not going to shut up on these issues. I'm going to keep fighting this fight," Homan said. "As an American, as someone who's enforced immigration law for 34 years, I'm concerned, I'm concerned about the future of this country."
