It appears that there is no end to the surprises coming from the US Congress. First House of Representatives Speaker John Boehner invites Israeli Prime Minister Netanyahu to speak before the joint houses of Congress which leads to weeks of accusations, denunciations, defiance, and other emotions (some even genuine) too numerous to mention here.
Just as that furor is dying down after the speech is actually delivered, forty-seven Republican senators issue an open letter directed to the Iranian leadership, warning them that the Senate will oppose any deal signed by the six powers and Iran that the Senate finds inadequate. This was followed by Administration outrage and the same series of denunciations, defenses, accusations, etc. as with “The Speech.”
