The Senate has delayed voting on the nomination of Ron Vitiello to lead the Immigration and Customs Enforcement agency. Vitiello, who currently serves as the acting director of ICE, has come under fire for refusing to rule out future family separations at a hearing earlier this month. He has also been called out for a 2012 tweet in which he said the Democratic Party should be renamed the “Neo-Klanist party.” This comes as a new report from ProPublica reveals that families are still being separated at the border, months after the policy was supposedly reversed.
