Donald Rumsfeld, the former U.S. Secretary of Defense, told the Daily Mail that he plans on voting for presumptive Republican nominee Donald Trump. Rumsfeld said the decision between backing Trump or presumptive Democratic nominee Hillary Clinton was "not a close call." "I'm a Republican, and there's not any doubt in my mind how I'll vote," Rumsfeld said. "I don't believe Hillary Clinton is qualified to be President of the United States." The same day, Brent Snowcroft, a former national security adviser for George H.W. Bush endorsed Clinton.
