Comedian and actor Rosie O’Donnell has responded to President Donald Trump 's threat to have her U.S. citizenship revoked, the latest move in a yearslong back-and-forth between the two New York-born former TV stars.

A federal judge in New Hampshire says he will certify a class action lawsuit including all children who will be affected by Trump’s executive order ending birthright citizenship.

The president on Saturday threatened to revoke comedian Rosie O'Donnell's U.S. citizenship, something he cannot legally do.

Removing O'Donnell's citizenship would be unconstitutional, as the 14th Amendment grants citizenship to all those born in the United States.

President Donald Trump says he is considering revoking actress and comedian Rosie O’Donnell’s U.S. citizenship.
