Donald Trump took to Twitter and attacked Oprah Winfrey, challenging her to run for office.

The rant came after she moderated a 60 Minutes segment with a diverse group of voters from Michigan, discussing Trump.

“Just watched a very insecure Oprah Winfrey, who at one point I knew very well, interview a panel of people on 60 Minutes. The questions were biased and slanted, the facts incorrect,” Trump tweeted on Sunday night. “Hope Oprah runs so she can be exposed and defeated just like all of the others!”
