Rosie O’Donnell has to adhere to some strict rules during her hosting stint on Jimmy Kimmel Live!, the actress revealed. On Monday’s On with Kara Swisher, O’Donnell told the host that she has been preemptively banned from singing a parody song about her longtime nemesis, Donald Trump. “I have been told I’m not allowed to do that,” O’Donnell told a stunned Swisher. Trump once shared a meme depicting five photos of Rosie O’Donnell as the stages of “Trump Derangement Syndrome.” She also told Swisher she hopes to emulate the TV anchor during her tenure on his show.
