“We lost a brother Yesterday. We will truly miss you, Mike,” he wrote in a since-deleted tweet, according to the Post. “Thinking of some of the great times we all spent together. Everything I saw you do. Was built in passion. I loved connecting again with you. Hearing about your children and the life you and your wife have built. I’m sending all the prayers and love to your family brother.”
