I hadn't how realized prevalent their revealing their secrets in television shows and movies was even back in the 1960s. Check out this Batman show from 1966 at 15:10 minutes.
John Kerry (Skull & Bones 1966) faced off against George W. Bush (Skull & Bones 1968) in the 2004 US presidential election, the first time two Bonesmen had run against one another for that office.
George H.W. Bush was also a Skull & Bones member.
No doubt a Bonesman had a hand in producing the Batman television series.
