Senator John Fetterman , a Pennsylvania Democrat, on Sunday supported Immigration and Customs Enforcement (ICE) agents being allowed to wear masks that help conceal their identities. “Some of those agents wearing masks, primarily that’s driven by people who are going to dox those people. That’s a serious concern too, absolutely. They can target their families,” the senator said while appearing on Fox News’ The Sunday Briefing . “Don’t ever, ever dox people and target their families too.”
