Trump and Warren have long maintained a fraught relationship.

Trump's campaign went after Warren shortly before she formally announced her intentions to run for the White House, attacking the Democratic senator for her claims to Native American heritage and saying that she would be rejected by the American people for "her dishonest campaign and socialist ideas, like the Green New Deal, that will raise taxes, kill jobs and crush America's middle class."

Trump early on latched on to Warren's previous claims of Native American ancestry, often questioning them and disparagingly referring to her as "Pocahontas."

Warren, a vocal Trump critic, sought in October to get out in front of criticism originating from those claims by publicizing the results of a DNA test. The results purported "strong evidence" that she had Native American ancestry, likely from a distant ancestor, but the move drew sharp criticism from many Native Americans and advocates, prompting her to issue multiple apologies.

“This is our family’s story, and it’s all consistent from that point in time. But as I said, it’s important to note I’m not a tribal citizen, and I should have been more mindful of the distinction,” Warren told reporters last month.
