Where did you hear such a thing?
Not a chance.
I had met Dr Keyes when he stopped in Williston, North Dakota, on the campaign trail in '96. He gave an impressive talk, and is the only candidate to have stopped in Williston during my lifetime.
I remember being shocked/disapointed at him expressing such views in the TV interview a few years later, and hopefully have it wrong. But that is what I recall.
