Washington (CNN) President Donald Trump said in an interview aired Sunday that he's not prepared to lose the 2020 presidential election.

"It would be much better if I said, 'Yeah.' It would be much easier for me to say, 'Oh, yes.' No, I'm probably not too prepared to lose. I don't like losing. I haven't lost very much in my life," Trump told NBC's "Meet the Press."

Trump also subsequently reasserted that he doesn't "believe" in the validity of "a lot" of votes cast which show he lost the popular vote in 2016 to Hillary Clinton.

"I'll say something that, again, is controversial. There were a lot of votes cast that I don't believe," Trump said.
