US President Donald Trump has said he is considering revoking talk show host Rosie O’Donnell’s American citizenship after she criticised his administration’s response to the deadly floods in Texas.In a post on his social media platform Truth Social on Saturday, Trump wrote: “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.”He added: “She is a Threat to Humanity, and should remain in the wonderful Country of Ireland, if they want her. GOD BLESS AMERICA!”Can Trump revoke citizenshipO’Donnell, who was born in New York, cannot legally have her citizenship revoked by the president. Under US law, a person born in the country cannot be stripped of their citizenship by the government.O’Donnell, who moved to Ireland earlier this year with her 12-year-old son, posted a TikTok video blaming Trump’s budget cuts to weather and environmental agencies for worsening the effects of the Texas floods. “What a horror story in Texas,” she said. “And you know, when the president guts all the early warning systems and the weathering forecast abilities of the government, these are the results that we’re gonna start to see on a daily basis.”She posted two messages on Instagram, saying Trump attacks her because she “stands in direct opposition with all he represents.”Trump and O’Donnell have publicly clashed for nearly 20 years, beginning in 2006 when O’Donnell, then a host on The View, mocked Trump’s handling of a Miss USA pageant controversy.Story continues below this adWho all has Trump threatened on citizenshipThis is not the first time Trump has raised the idea of removing someone’s citizenship.
