President-elect Donald Trump and Rosie O'Donnell have publicly feuded in the past, and with less than three weeks until the inauguration, O'Donnell is stepping up her game.

In a series of tweets over the weekend, O'Donnell calls out Trump as being a "sick man" and a "criminal" who is "mentally ill" and "mentally unstable," as well as being the world's "worst human."

O'Donnell tweeted a link to a story about how Trump asked a biographer to leave his golf course this weekend. Trump was reportedly upset with what the biographer wrote about his divorce from first wife Ivana Trump.

Recently, O'Donnell received criticism for sharing a video alleging Trump's 10-year-old son, Barron, has autism. She later apologized.
