Washington (CNN) Our weekly roundup of the news, notes and chatter about the prospects for the next Democratic presidential race:

President Donald Trump made headlines -- and offered a glimpse at what his 2020 campaign is going to look like -- with a two-for-one swipe at the #MeToo movement and Massachusetts Sen. Elizabeth Warren during his rally in Montana on Thursday night.

Trump was out west to pump up Matt Rosendale, the Republican running to unseat Democratic Sen. Jon Tester in November. But as with most of Trump's speeches on the midterm campaign trail, it was less about the candidate and more about the speaker and his grievances.

Trump again called Warren "Pocahontas," attacking her claims of Native American heritage and saying he wants her to take a DNA test. He even said he'd throw one at her on a presidential debate stage. "We'll take that little kit and say -- we have to do it gently because we are in the Me Too generation -- and we will very gently take that kit, slowly toss it" to her, Trump said.

Warren fired back at Trump on Twitter, calling up the ongoing family separation crisis at the border. "While you obsess over my genes, your Admin 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," she wrote. "Maybe you should focus on fixing the lives you're destroying."
