But when Joe Wilson yelled "you lie" to Obama, he was lambasted and forced to eventually apologise.
On September 9, 2009, Wilson shouted at President Barack Obama while Obama addressed a joint session of Congress to outline his proposal for reforming health care. During his address, Obama said: "There are also those who claim that our reform effort will insure illegal immigrants. This, too, is false – the reforms I'm proposing would not apply to those who are here illegally." In a breach of decorum,Wilson pointed at Obama and shouted, "You lie!" twice. Wilson attracted national and international attention for the incident. He said afterwards that his outburst reflected his view that the bill would provide government-subsidized benefits to illegal immigrants.
Then-White House Chief of Staff Rahm Emanuelimmediately approached senior Republican lawmakers and asked them to identify the heckler and urge him to apologize immediately. Members of Congress from both parties condemned the outburst. "Totally disrespectful", said Senator John McCain (R-Arizona) of Wilson's utterance. "No place for it in that setting or any other and he should apologize immediately."
House Democrats called on Wilson to issue a formal apology on the House floor. House Majority Whip Jim Clyburn who led the resolution said "This is about the rules of the House", while House Majority Leader Steny Hoyer said "What's at issue here is of importance to the House and of importance to the country ... This House cannot stay silent". Wilson refused to make an apology in the House, saying in a televised interview that, "I believe one apology is sufficient." Congressional Republicans agreed, and opposed further action, with Minority Leader John Boehner saying "I think this is a sad day for the House of Representatives ... I think this is a political stunt aimed at distracting the American people from what they really care about, which is health care."On September 15, the House approved a "resolution of disapproval" against Wilson, on 240–179 vote.
