Trump says he is considering revoking Rosie O'Donnell's U.S. citizenship

President 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.

"Because of the fact that Rosie O'Donnell is not in the best interests of our Great Country, I am giving serious consideration to taking away her Citizenship," Mr. Trump wrote in a social media post on Saturday. He added that O'Donnell, who moved to Ireland in January, should stay in Ireland "if they want her."

The two have criticized each other publicly for years, an often bitter back-and-forth that predates Mr. Trump's involvement in politics. In recent days, O'Donnell on social media denounced Mr. Trump and recent moves by his administration, including the signing of a massive GOP-backed tax breaks and spending cuts plan.
