President Trump once again attacked sparring partner Sen. Elizabeth Warren (D-MA) Monday in an interview with Fox News’ Pete Hegseth, according to an excerpt of the interview tweeted just hours after Warren announced that she was forming an exploratory committee to consider running for president in 2020. “She did very badly in proving that she was of Indian heritage,” Trump said, according to a tweet from Fox News White House correspondent Kevin Corke. “That didn’t work out too well. I think you have more than she does, and maybe I do too and I have nothing.” Trump added, “I wish her well, I hope she does well, I’d love to run against her.” He then pivoted to attacking the senator’s mental health. When asked by Hegseth if Warren really thinks she could win against him in 2020, Trump reportedly responded, “Well, that I don’t know. You’d have to ask her psychiatrist.”
