In this clip from a Senate Foreign Relations Committee hearing, a seemingly confused Sen. Marco Rubio (R-FL) innocently asked Secretary of State John Kerry to tell him “why he’s wrong” in claiming that the Obama Administration’s military strategy against ISIS is influencing negotiations with Iran.

He probably shouldn’t have done that. Kerry went on to school him on global affairs, peace-building, negotiation tactics, and current events, exposing him as the fraudulent political amateur that he is.
