WASHINGTON (CNN) - Shouting from the audience. Holding up signs blasting the health care reform bill before Congress. Frequent hissing and booing.
hough it sounds like behavior at one of the health care town hall meetings last month, it was how some Republicans reacted to President Obama's speech to a joint session of Congress on Wednesday night.
But Norm Ornstein, a longtime observer of Congress and an expert at the American Enterprise Institute, said the tone and behavior from members of Congress are not necessarily new.
"A lot of what went on [Wednesday] night has become fairly typical of what we've seen in the State of the Union messages over the last 10 or 12 years, where it's one side jumping up wildly and the other side sitting on their hands in stony silence."
The most memorable moment came from Rep. Joe Wilson, R-South Carolina, who shouted "You lie" after the president said that a Democratic-sponsored health care bill would not cover illegal immigrants.
Ornstein said that in addition to being beyond the bounds of what is typical, Wilson's comment is "just sort of stunning in the level of disrespect for not just the president but the presidency."
During several moments in Obama's speech, members of the GOP hissed and yelled at the president as he laid out his plan for reform. One Republican wore a sign around his neck saying, "What bill?"
House Minority Whip Eric Cantor, R-Virginia, was seen several times typing on his phone during the speech.
