Roger Clemens, Andy Pettitte and their former strength coach Brian McNamee were invited by a congressional committee Friday to testify at a hearing on the Mitchell Report on the use of performance enhancing drugs in baseball. Kirk Radomski, a former New York Mets clubhouse attendant, and former All-Star Chuck Knoblauch were also asked to appear before the House Oversight and Government Reform Committee. Radomski’s allegations were central to the findings released last month by Senator George Mitchell. Clemens' attorney, Rusty Hardin, said in a statement that “Roger is willing to answer questions, including those posed to him while under oath.”
