A Massachusetts sheriff testifying before Congress on Tuesday called for elected leaders of sanctuary cities to be arrested.

Bristol County Sheriff Thomas Hodgson told members of the House Judiciary Committee that sanctuary cities have become "magnets" for illegal immigrants, some of whom are violent criminals.

“Our citizens would be safer if we never stopped enforcing immigration law and if we never formed or turned a blind eye toward sanctuary cities,” Hodgson said.

“If these sanctuary cities are going to harbor and conceal criminal illegal aliens from ICE, which is in direct violation of Title 8 of the U.S. Code, federal arrest warrants should be issued for their elected officials,” Hodgson declared.

Hodgson singled out Massachusetts State Rep. Michelle DuBois (D), who posted an online warning to illegal immigrants about an upcoming Immigration and Customs Enforcement (ICE) "raid."

“This is the most outrageous, outrageous example of what is going on across the United States that is undermining my job and every other law enforcement officer in the United States,” Hodgson said.

Hodgson told Neil Cavuot that he "can't think of anything more irresponsible than what [DuBois] did. She ought to be ashamed of herself. She should be looked at for a minimum of ethics violations."

"I'm sure there's some review of whether or not she compromised some investigation involving ICE," he said.
