Immigration and Customs Enforcement agents have in recent days deported the Cuban-born mother of a 1-year-old girl — separating them indefinitely — and three children ages 2, 4 and 7 who are U.S. citizens along with their Honduran-born mothers, their lawyers said Saturday.

The three cases raise questions about who is being deported, and why, and come amid a battle in federal courts over whether President Donald Trump’s immigration crackdown has gone too far and too quickly at the expense of fundamental rights.

Lawyers in the cases described how the women were arrested at routine check-ins at ICE offices, given virtually no opportunity to speak with lawyers or their family members and then deported within three days or less.
