"I apologize unreservedly to Shay Pierce. What I said about him was untrue and unkind. I regret that we X", where X is the mistake he feels he made in handling Pierce's situation.
"I apologize unreservedly to Shay Pierce. What I said about him was untrue and unkind. I regret that we X", where X is the mistake he feels he made in handling Pierce's situation.
