As noted in the story, he privately committed to Pittman on March 12.
He reached out to me at 1:59 am on the 13th and said he committed and would announce it at 8 am with a graphic that day. I got quotes and was ready to go. He talked to people close to him and was urged to go through the process a bit more.
So when it came time to go public he chose to do so on his late grandfather’s birthday.
