I think Rahm Emanuels's quote, in response to Rep. Joe Wilson's (R-SC) "You lie!" outburst, pretty much says it all.
After the speech, Rahm Emanuel, the White House chief of staff, approached lawmakers on the floor to ask who had accused Mr. Obama of lying. Mr. Emanuel was told it was Representative Joe Wilson, Republican of South Carolina.
"No president ever has been treated like that, ever," Mr. Emanuel told reporters.
