Last week a subcommittee hearing entitled "Perspectives in Mixed Martial Arts" was held by the Energy and Commerce Committee in the House of Representatives. The two-hour proceeding saw a wide range of subjects important to the future of MMA discussed. (The full list of witnesses and copies of their prepared statements can be found here) This included traumatic brain injury, drug testing, athletic commission oversight, competition between promotions, the means by which rankings and titles were awarded, and whether the passage of HR 44 - the Muhammad Ali Expansion Act Bill - was needed to protect fighters.
