Rudolph Giuliani (R-NY) (5/28/44) - Did not serve; received a deferment in 1968 for a clerkship with a United States District Court judge. Got a letter from the judge to sustain this deferment, after receiving student deferments for college and law school.

Former mayor Rudy Giuliani
Draft Status: Special deferment via federal-judge clerkship.
Wartime Activities: A 1968 NYU Law grad, Giuliani went to work for the U.S. Attorney’s Office in 1970.
Bingo, that's exempt. And the draft was about over.
1968 to 1970, it was nice of the judge. My guess Rudy wasn't hanging in Haight-Ashbury
