Why can’t Columbia settle this?
Perhaps for the same reason that Queens and Kapiolani Hospitals each saying they had no record of Barry Soetoro/Obama's birth at their respective hospitals didn't settle it.
Perhaps you recall that anyone who doubted Barry was born in Hawaii has for a decade been slapped with the pejorative, "birther"! Even The Donald seemingly got knocked out of his 2011 presidential exploratory venture with Barry's 1-2 punch of birtherism, and "Official Hawaii" birth certificate roast at the 2011 White House Correspondents Dinner.
The CIA's fake narratives are not easily overcome. George Steppenalloverus was a Columbia polysci grad, ostensibly just one year behind Barry. Georgie probably worked the leverage he had over Barry that he somehow never bothered to disclose.
