Big changes planned for ICE, Mayorkas says, as deportations, arrests drop Homeland Secretary Secretary Alejandro Mayorkas says he wants to make "significant changes" to Immigration and Customs Enforcement (ICE) -- an agency that has seen a rapid reduction in its enforcement scope and has seen arrests and deportations of illegal immigrants plummet since President Biden took office. Mayorkas told The Washington Post his agency was conducting a review of ICE and its priorities, and that he expects "significant changes" when that review is complete. "What those changes will be, I am wrestling with right now, quite frankly," Mayorkas said, the newspaper reported.
