President Donald Trump said he was weighing using the power of the government against one of his longtime entertainment world nemeses, comedian and actress Rosie O’Donnell, threatening to revoke her citizenship.

Shortly before 10 a.m. Saturday, Trump said on Truth Social, “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.”

The president called O’Donnell a “threat to humanity” and said she should stay in Ireland, where she moved to in January after Trump won a second term.

O’Donnell snapped back at Trump..

“The president of the USA has always hated the fact that I see him for who he is — a criminal con man sexual abusing liar out to harm our nation to serve himself,” she said.

Experts said the president does not have the power to take away the citizenship of a U.S.-born citizen.
