Rep. Trey Gowdy (R-S.C.) was on “The Kelly File” tonight, where he sounded off on Jonathan Gruber’s admission that a “lack of transparency” and the “stupidity of the American voter” helped pass ObamaCare.

This was not the first time Gruber called the American people stupid, with another new clip surfacing of Gruber calling Americans “too stupid to know the difference.”

“I can’t get past the irony to even get to the arrogance,” he said, remarking that the “most transparent administration” had to use deception to get its legislation passed.

Gowdy slammed Gruber for insulting the people who put the president in office not once, but twice.

“We were sold a false bill of goods … and they’re laughing all the way to the bank,” he said of ObamaCare.

Gowdy had a warning for Americans: keep this in mind the next time anyone tries to sell you a comprehensive piece of legislation.

“Comprehensive is Latin for ‘there’s lots of bad stuff in here,’” he said.

Gowdy had a message for his fellow citizens: fool me once, shame on you, ever fool me again, shame on us.
