President Donald Trump reignited a decades-long feud with comedian Rosie O’Donnell Saturday, taking to his Truth Social platform to write he was considering revoking her 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.”

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.

The ACLU filed the lawsuit on behalf of a pregnant immigrant, undocumented parents, and their U.S.-born children.

A federal judge agreed to issue a new nationwide block against President Donald Trump’s executive order seeking to end birthright citizenship. A CNN panel discusses the ruling from US District Judge Joseph Laplante which issues a widespread block of the order through class action lawsuits.
