President Trump's pick to run Immigration and Customs Enforcement (ICE) on Tuesday called for a crackdown on so-called sanctuary cities, saying politicians who help run them should be charged with crimes.

In an interview with Fox News' Neil Cavuto, ICE Acting Director Thomas Homan said the Department of Justice needs "to file charges against the sanctuary cities" and "hold back their funding."

Homan, who was announced in December as President Trump's pick to permanently run the agency, went on to say that politicians enforcing sanctuary city policies need to be held "personally accountable."

"We gotta take [sanctuary cities] to court, and we gotta start charging some of these politicians with crimes," he said.
