Who is the coo of WWE?

Until about two months ago it was Vincent McMahon. As part of WWE's storyline, he was fired by the board of directors and replaced by Triple H.
Last week Triple H was relieved of his duties and the Vice President of Talent Relations, John Laurinitis took over as the COO

Vince was never COO he is the Chairman of the board and still owner of the WWE. HHH is still COO he was replaced as General Manager over RAW. Vice Presided of Talent Relations is not the COO he is only GM of RAW
