President Donald Trump says he is considering “taking away” the U.S. citizenship of a longtime rival, actress and comedian Rosie O’Donnell

President Donald Trump unleashed on Rosie O'Donnell, his longtime foe and former co-host of "The View," threatening to revoke her U.S. citizenship.

Trump’s executive order, signed in January, seeks to deny citizenship to children who are born to people who are living in the U.S. illegally or temporarily. It is part of the hard-line immigration agenda of the president, who has called birthright citizenship a “magnet for illegal immigration.”

Birthright citizenship may change in the US, and could impact the ability of certain individuals to travel as of July 27.

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.
