Here is more from ESPN:
It was nearly an hour later by the time the network had officially announced all 68 teams, with Syracuse getting in and Monmouth -- and its entertaining bench players -- missing out.
In talking with ESPN, a CBS spokesperson said the network would have no comment on the bracket being leaked on the Internet.
By the way, that CBS Selection Show was absolutely a debacle. It was terrible to watch and NBA guys, who clearly have watched no college basketball, were trying to discuss things that they had no clue about.
Sounds to me someone leaked the NCAA bracket just to make a point to CBS about its 2 hour show lol— Jim Utter (@jim_utter) March 13, 2016
