The Bay State's senior senator is again facing pressure to prove her claim that she is a Cherokee Indian.

President Donald Trump, who has taken to referring to U.S. Senator Elizabeth Warren (D-Massachusetts) as Pocahontas, is challenging the potential 2020 presidential candidate to take a DNA test. Warren has claimed Indian heritage, though ranking members of Cherokee Nation say there is no evidence to support those claims.

It has been alleged, though not proven, that Warren claimed Native American ancestry to give her an advantage on employment applications. She has denied it.

During a rally in Montana, Trump challenged Warren to prove her ancestry:

“And we will say, ‘I will give you a million dollars, paid for by Trump, to your favorite charity if you take the test and it shows you’re an Indian. And we’ll see what she does. I have a feeling she will say no but we will hold it for the debates.'”

Warren responded on Twitter, but didn't indicate if she'd accept Trump's challenge:

Warren is certainly under no obligation to take a DNA test or to open her employment records no more than Trump is required to release his tax returns. But one might argue that if she is telling the truth, it would certainly defuse the situation immediately. If she continues to refuse to resolve the issue, it could be problematic for her with voters later on by forcing her to remain on the defensive.

Yikes! And just think, the election is still two years away. This could be a lot of fun.
