A veteran Republican senator set off a Twitter firestorm over the weekend by calling President Obama "stupid" for his recent comments on the Supreme Court health care case.
Sen. Chuck Grassley of Iowa wrote: "Constituents askd why i am not outraged at PresO attack on supreme court independence. Bcause Am ppl r not stupid as this x prof of con law."
Grassley, the ranking Republican on the Senate Judiciary Committee, was referring to the president's controversial statement last week that a ruling against his health care law by the high court would amount to "judicial activism" by "unelected" justices.
Top Obama political adviser David Axelrod quickly fired back, mocking the senator's peculiar Twitter writing style.
"Heads up, Sen. Grassley. I think a 6-year-old hijacked your account and is sending out foolish Tweets just to embarrass you!"
