President Trump just wrapped up a rally in Great Falls, Montana, where he definitely went off script and … well, you know how he is when he goes off script.

One crowd-pleasing moment was when Trump said that if his Democratic opponent in 2020 was Sen. Elizabeth Warren, he’d offer her $1 million to take a DNA test.

That’s just amazing trolling.
