Sen. Elizabeth Warren claps back at Donald Trump “obsessing” over her genes during a rally in Montana, saying, “your Admin is conducting DNA tests on little kids.”

Trump said if Warren was the Democratic presidential nominee, during a debate he would offer her $1 million to take a test to prove her Native American heritage.

“But let’s say I’m debating Pocahontas, I’ll do this,” Trump. “I promise you I’ll do this, you know those little kits they sell on television for $2? Learn your heritage,” Trump said.

Warren tweeted: “Hey @realDonaldTrump: While you obsess over my genes, your Admini is conducting DNA tests on little kids because you ripped them from their mamas & you are too incompetent to reunite them in time to meet a court order. Maybe you should focus on fixing the lives you’re destroying.”
