WASHINGTON, Sept 19 (Reuters) – A U.S. senator compared Iranian President Mahmoud Ahmadinejad to Hitler and made fun of his name on Tuesday during a congressional hearing on the U.S. strategy to end Iran’s suspected nuclear weapons program. “Ahmadinejad — I call him Ahmad-in-a-head — I think he’s a Hitler type of person,” Ohio Republican Sen. George Voinovich said during a Senate Foreign Relations Committee hearing. “He has made it clear that he wants to destroy Israel. He has made it clear he doesn’t believe in the Holocaust. He’s a, he’s a — we all know what he is,” the senator added.
