Upstate Congressional member Louise Slaughter just reminded her fellow members about what goes for conduct at the House of Representatives, in the wake of the Rep. Joe Wilson "you lie" moment. According to Politico's Glenn Thrush, "Especially useful: The section on how to properly insult the executive branch in the in the chamber. 'Disgrace" and "nitwits' -- okay. 'Liar' or 'sexual misconduct' -- ixnay."
Under section 370 of the House Rules and Manual it has been held that a Member could:
• refer to the government as “something hated, something oppressive.”
• refer to the President as “using legislative or judicial pork.”
• refer to a Presidential message as a “disgrace to the country.”
• refer to unnamed officials as “our half-baked nitwits handling foreign affairs.”
Likewise, it has been held that a member could not:
• call the President a “liar.”
• call the President a “hypocrite.”
• describe the President’s veto of a bill as “cowardly.”
• charge that the President has been “intellectually dishonest.”
• refer to the President as “giving aid and comfort to the enemy.”
• refer to alleged “sexual misconduct on the President’s part.”
