We have no idea what's going on here, but it sounds pretty exciting. Also, we hope these young women knew what they were getting into when they became the Chuck Grassley Dance Team.

This really doesn't help. "Grass$ey"? "The ATL"? Was Chuck in a rap video?

We were going to post after the jump an old Grassley video his people put on YouTube that featured him, among other humorous things, jogging, but it appears to have been taken down. (WHAT'S GRASSLEY HIDING?) Instead, you can watch these! Preferably all at the same time.

We think he may be holding some town meetings. Not sure. [Twitter]
