Mitt Romney: Arab Spring Can't Turn Into Arab Winter

Responds to assault on embassy in Benghazi and killing of the U.S. ambassador

Republican presidential candidate Mitt Romney says it's never too early for America to condemn attacks on its sovereignty and says the White House gave "mixed signals" in its response to the breach of the American embassy in Egypt.

Romney on Wednesday condemned attacks against the American consulate in Benghazi, Libya, that killed four U.S. diplomats, including the U.S. ambassador.
