In a letter sent February 27 to Attorney General Michael Mukasey, House Oversight and Government Reform Committee chairman Henry Waxman and ranking Republican Tom Davis said Clemens's testimony that he "never used anabolic steroids or human growth hormone warrants further investigation". As a result of the Mitchell Report, Clemens was asked to end his involvement with the Giff Nielsen Day of Golf for Kids charity tournament in Houston that he has hosted for four years. As well, his name has been removed from the Houston-based Roger Clemens Institute for Sports Medicine and will be renamed the Memorial Hermann Sports Medicine Institute.
