Donald Trump Jr. hopped on the Montana campaign trail Friday with tech entrepreneur Greg Gianforte, who is gunning for Interior Secretary Ryan Zinke's vacated House seat.

Don't forget: Last year Gianforte failed to win a bid for the governor's seat to a Democrat.

Why it matters: All eyes are on Montana after the GOP won by a narrower margin than usual in the Kansas special election and now that the Georgia special election is headed to a hotly contested runoff. Like Kansas and Georgia, the seat is usually a shoo-in for GOP candidates, but the DCCC announced their six-figure investment Thursday, ramping up the stakes for Gianforte.

Context: Trump Jr. is following in his father's footsteps; President Trump robo-called for both candidates in Kansas and Georgia.

Prairie dogs: You read that right. Trump Jr. and Gianforte are hunting prairie dogs later today — Jr. is an avid hunter — although the Humane Society of the United States condemned it, per the AP.
