Rep. Steve King (R-Crazy Caucus) for this:
The King Amendment would essentially prevent states from developing strong independent health, safety, and cruelty standards, even if local voters want them. [...]
King, though, brags that his legislation “wipes out everything they’ve [animal rights advocates] done with pork and veal.”
Whoopee! Big win for defiant mouth-breathers whose greed and gluttony requires animal torture in order to be adequately sated.
Adding... So much for the right-wing dogma of leaving things like this up to the states.
