(CNN) – Republican Sen. Chuck Grassley of Iowa, who has long been an outspoken critic of President Barack Obama, used scathing language in a tweet Saturday to condemn the president's remarks about the Supreme Court last week.
"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 wrote, using typical shorthand for the social networking website.

Responding to the message, Obama campaign senior strategist David Axelrod, himself a prolific tweeter who often engages critics of the president, blasted the Iowa senator.
"Heads up, Sen. Grassley. I think a 6-year-old hijacked your account and is sending out foolish Tweets just to embarrass you!" Axelrod wrote.
Obama last Monday was asked about measures his administration was taking in the event the United States Supreme Court determines his health care law is unconstitutional. The high court heard oral arguments on the law in late March. Obama said such a decision would be "unprecedented."
"I'm confident that the Supreme Court will not take what would be an unprecedented, extraordinary step of overturning a law that was passed by a strong majority of a democratically elected Congress," the president said.
