Chris Christie, the N.J. governor, can dish all he wants about his weight – but he doesn’t like it when others do, even physicians who once took care of U.S. presidents.

On Wednesday, Dr. Connie Mariano of Scottsdale, Arizona, who served nine years as White House physician (she was Bill Clinton’s personal physician), told CNN she worries Christie could die in office because of his weight – and that he’s at risk of heart attack or stroke.

The plaintalking governor didn’t like that “diagnosis from afar.” He responded angrily that unless Mariano gets on a plane, gives him a physical exam in person and takes his full medical and family history, “she should shut up.”
