President Donald Trump has threatened to strip his longtime nemesis Rosie O’Donnell of American citizenship—something he has zero power to do.

Class actions let people facing a common problem band together in a single lawsuit to obtain nationwide relief.

Legal advocates fighting the president's order to restrict citizenship from babies born to certain immigrants are turning to class action lawsuits to stop his policy.

President Donald Trump says he is considering “taking away” the U.S. citizenship of a longtime rival, actress and comedian Rosie O’Donnell, despite a decades-old Supreme Court ruling that expressly prohibits such an action by the government.
