Claiming that the Trump administration has stopped following laws directed at reunifying detained immigrant children with their families, the New York Civil Liberties Union has sued on behalf of a Long Island teenager, originally from El Salvador and accused of being a gang member, who has been locked away for more than seven months.

The class action lawsuit falls into a series of legal actions launched by the NYCLU over the last year that aim to combat what it says is the administration’s illegal treatment of undocumented immigrants.
