NBC NEWS- Seven-time Cy Young winner Roger Clemens will be investigated by the U.S. Justice Department.

The Congressional Oversight and Government Reform Committee wants to know whether Clemens committed perjury when he testified before a congressional committee on illegal drugs in sports.

During the hearing on February 13, Clemens said, "Once again, I never took steroids or human growth hormone"

The Congressional Committee investigating the use of steroids and performance enhancing drugs in professional baseball asked the Justice Department to look into whether Clemens committed perjury and knowingly made false statements at the public hearing and in a deposition.

The pitcher's denials clash with his former trainer Brian McNamee, who testified at the hearing he injected Clemens with steroids and human growth hormone, or HGH.

Clemens statements also contradict his former teammate Andy Pettitte who gave sworn testimony Clemens admitted to him he had taken HGH.

The investigation stems from the release in December of the Mitchell Report, which linked Clemens, Pettite and other baseball stars to the use of performance enhancing drugs.

At spring training camp, Pettitte once again admitted using HGH and apologized for tainting the sport.

Pettite said, “It was stupid, I was desperate. I wish I never did it. I don't consider myself a cheater.”

As news of the perjury probe broke, professional league leaders Wednesday were testifying before a separate House committee looking into whether professional leagues are doing enough to ban and test for steroids use.

Major League Baseball Commissioner Bud Selig said, "MLB has acted aggressively to combat the use of performance enhancing drugs."

But lawmakers aren't convinced high school athletes, who look up to professional sports stars are getting the message.

The message that the use of performance enhancing drugs is not the way to get a competitive edge and are considering federal legislation that would create drug testing standards for all sports.

In January, Illinois became the fourth state, behind New Jersey, Texas and Florida to implement programs requiring high school athletes to be tested for performance enhancing drugs at certain times during the playing season.
