Donald Trump is at it again.
In his latest Twitter rant, he's had a go at none other than Oprah Winfrey - or "insecure" Oprah Winfrey as he referred to her in the tweet.
It's after she appeared on a US TV show, which Trump was obviously watching.
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. Hope Oprah runs so she can be exposed and defeated just like all of the others!— Donald J. Trump (@realDonaldTrump) February 19, 2018
Despite encouraging her to run so "she can be defeated just like all the others", Oprah doesn't seem that keen on the presidency despite rumours she might go for it.
Speaking to 60 Minutes, she said “I am actually humbled by the fact that people think that I could be a leader of the free world, but it's just not in my spirit, it's not in my DNA".
