The Supreme Court's limit on nationwide injunctions still allows them in class action suits.When did Donald Trump and Rosie O'Donnell start feuding?Trump's feud with O'Donnell goes back a couple of decades. In a 2016 presidential debate between Trump and Hillary Clinton, moderator Megyn Kelly noted that he'd referred to women he doesn't like as "fat pigs, dogs, slobs, and disgusting animals." He replied, "Only Rosie O'Donnell."At that time, he had a decade-long history of slurring O'Donnell, calling her "obnoxious" and "dumb" and saying she "talks like a truck driver" and has a "fat, ugly face." In the same debate, he claimed O'Donnell had been "vicious" to him, having first criticized him when she was a cohost on The View. O'Donnell hasn't let up on Trump since she moved to Ireland. Recently, she posted that he "has put this country in danger" and said federal cuts to weather forecasting contributed to the deaths from floods in Texas, as reported by Deadline and other outlets.This story is still developing
