Speaking at a rally in Montana on Thursday, President Trump made an offer to one of his biggest critics, and potential challenger in 2020. It has been widely reported that Senator Warren fibs about her Native American heritage, and Trump called her out on it, again.

According to The Hill:

President Trump said Thursday that if he were facing Sen. Elizabeth Warren (D-Mass.) 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 said during a campaign rally in Great Falls, Mont., referring to Warren by the racially charged nickname he gave her during the 2016 presidential campaign.

…

“We will take that little kit, we have to do it gently because we’re in the “Me Too” generation, we have to be very gentle,” Trump said mocking the movement that seeks to expose sexual misconduct in media, entertainment and politics.

“We will very gently take that kit and we will slowly toss it, hoping it doesn’t hit her and injure her arm, even though it only weighs probably 2 oz,” he said.

Experts have weighed in to disprove Senator Warren’s claims in the past, and this is another angle for Trump to go on the offensive. It will be interesting to watch the 2020 campaign play out if Trump faces off against Warren.
