Bob Gates: Only Time I Saw Passion From Obama on Military Issues Was Combating Leaks, Don't Ask Don't Tell

More memoir material

Former Defense Secretary Robert Gates sharply questions President Obama's "passion" for military matters in his forthcoming memoir, and claims that practically the only time he saw that in the president was during his push to repeal "don't ask, don't tell." 

The former Pentagon chief said in an interview aired Sunday that he was "disturbed" by Obama's "absence of passion" when it came to his military strategy. But in the book, "Duty," reviewed by Fox News, Gates hit Obama harder—and in personal terms—by contrasting his style with that of former President George W. Bush.
