As part of Donald Trump‘s immigration crackdown, three U.S. citizen children were deported with their mothers by the New Orleans Immigration and Customs Enforcement (ICE) on Friday morning. One of the children was undergoing cancer treatment and one of the mothers is pregnant.

Both families had lived in the country for years and had ties to their communities, according to the American Civil Liberties Union (ACLU) of Louisiana, which warns that the circumstances of their sudden deportations raises grave due process concerns. The civil rights organization says that the first family was detained on Tuesday and the second family on Thursday, and that one of the mothers was given less than one minute on the phone before the call was abruptly dropped, after her spouse attempted to provide a phone number to legal counsel.
