Rosie O'Donnell and President Donald Trump's feud has lasted for two decades, and is currently escalating on both sides.

Rosie O’Donnell said she wasn’t surprised that President Trump threatened to revoke her US citizenship, claiming that she’s endured “20 years of abuse” from her longtime foe. The former talk show host took to social media Tuesday to slam the “absurd” attack after the president triggered a social media brawl with O’Donnell when he branded her a “threat to humanity” in a fiery post on his platform.
