I'm not sure we will ever know with even Bill O'Reilly and Ann Coulter defending his "privacy". Many do not want to know the "rest of the story".
I now wonder if he was enrolled in the Columbia Teachers College. That is not nearly as prestigious as being a graduate of Columbia University. Teachers College is almost the affirmative action segment of CU. Different totally from the rest of the school.
BLEEP THAT!
He's the ultimate PUBLIC FIGURE!
He should have no expectation of privacy, and should have been immediately forthcoming with any requested records.
