NEW YORK, Jan. 4 (UPI) -- Roger Clemens and the trainer who said he injected the star pitcher with steroids will be asked to testify before a U.S. congressional committee this month.
Others asked to appear Jan. 16 by the House Oversight Committee -- in addition to Clemens and the trainer, Brian McNamee -- were the pitcher's fellow big-leaguers Andy Pettitte and Chuck Knoblauch, The New York Times reported Friday.
Also called was former New York Mets clubhouse attendant Kirk Radomski.
MLB Commissioner Bud Selig, players union leader Donald Fehr and former U.S. Sen. George Mitchell, who recently released a report on a 20-month investigation into steroid use in baseball, are to testify a day earlier, on Jan. 15.
Clemens and Pettitte were teammates with the New York Yankees and Houston Astros. Knoblauch was an infielder in the majors.
Radomski told investigators he distributed performance-enhancing drugs to ballplayers, Mitchell's report said.
Clemens told "60 Minutes," slated to air Sunday on CBS, that injections given to him by McNamee contained the painkiller lidocaine and vitamin B12, the Times said.
The pitcher's claims contradicted statements made by McNamee in last month's Mitchell report.
Earl Ward, lead attorney for McNamee, disputed Clemens' version of events during an interview with the Times.
"The only injections (McNamee) ever gave Clemens were for steroids and human growth hormone," he said.
