WWE's McMahon served with subpoena by federal agents

Federal law enforcement agents executed a search warrant and served a federal grand jury subpoena to WWE Executive Chairman Vince McMahon last month, according to a regulatory filing. McMahon is also taking medical leave from the sports entertainment company following recent spinal surgery. That announcement comes as WWE reported better-than-expected revenue in the second quarter. The company saw an increase in ticket sales for live events, both domestically and overseas. It also reported an uptick in advertising and sponsorship revenue.
