Comedienne and actress Rosie O'Donnell has likened President Donald Trump's supporters to Nazis.
O'Donnell, 55, who has had a long-standing feud with Trump, made the remarks on Twitter, referring to the president as "Adolf Trump."
"If [you] stand next [to] and work with Adolf Trump yes, [you] f***ing are a Nazi," she wrote, according to Fox News.
O'Donnell also called on Republicans to disavow -- and possibly impeach -- Trump following his divisive response to the violent clashes that took place between white nationalist demonstrators and their opponents in Charlottesville, Virginia, on Aug. 12.
"Republicans -- this is on you -- every single one of you who stand by this madman -- do something -- denounce him -- file articles of impeachment," the comedienne tweeted.
O'Donnell's feud with Trump goes back more than a decade. In 2006, while O'Donnell was co-hosting "The View," she called Trump a "snake-oil salesman on Little House on the Prairie" and mentioned that he had gone bankrupt, according to CNN.
"[He] left the first wife -- had an affair," she said at the time. "[He] had kids both times, but he's the moral compass for 20-year-olds in America. Donald, sit and spin, my friend."
Trump responded by referring to O'Donnell as "a real loser" and "a woman out of control."
"You can't make false statements," he said. "Rosie will rue the words she said. I'll most likely sue her for making those false statements -- and it'll be fun. Rosie's a loser. A real loser. I look forward to taking lots of money from my nice fat little Rosie."
In 2011, after O'Donnell announced that she was going to marry Michelle Rounds, Trump tweeted that he felt "sorry for Rosie's new partner in love whose parents are devastated at the thought of their daughter being with Rosie -- a true loser."
To which O'Donnell responded: "Wow [you are] an a** in every way."
When O'Donnell was brought back as co-host of "The View" in 2014, Trump applauded the decision, but went on to describe O'Donnell as "crude, rude, obnoxious and dumb."
Later that year, O'Donnell said her back-and-forth with Trump "was the most bullying I ever experienced in my life."
"It was national, and it was sanctioned societally," she said, according to CNN. "Whether I deserved it is up to your own interpretation."
Their feud took on an even more "national" character during the first Republican presidential primary debate in August 2015, when moderator Megyn Kelly accused Trump of calling women "fat pigs," "dogs," "slobs" and "disgusting animals."
"Only Rosie O'Donnell," Trump quipped.
O'Donnell responded that night on Twitter, writing: "Try explaining that [to your] kids."
