The Hill notes that Trump claimed Warren, a top surrogate for 2016 Democratic presidential nominee Hillary Clinton, "was getting up with that craziness and that anger" in speeches on the campaign trail.
"I think she hurt Hillary Clinton very badly," Trump said. "I watched those speeches – the anger, the hatred, in her heart – and I said, 'Ya know, she's really bad for Hillary.'"
"Pocahontas would not be proud of her as her representative, believe me," Trump continued, resurfacing his campaign trail nickname for the Democratic senator.
Fox host Jesse Watters suggested that Warren, who is among several Democratic senators often floated as a possible 2020 contender, is "probably going to run against you."
"I hope so," Trump responded. "That would be a dream come true."
Warren ripped into Trump in various speeches during last year's campaign, and has remained a constant presence on Twitter going after Trump since he took office in late January.
