Chuck Grassley (R-Iowa) said he didn't know what the president meant.
“I don’t know what the president has in mind, and I don’t think I better comment until I have a discussion with the president on that,” Grassley said, when asked by reporters.
Then, seemingly catching himself, Grassley added: “And I don’t intend to have a discussion with the president on that point, and I hope he doesn’t call me and tell me the same thing that you said he said.”
