Roger Clemens Pleads Not Guilty To Charge Of Lying

Baseball great Roger Clemens entered a not guilty plea Monday to charges of lying to Congress about whether he used steroids or human growth hormone.

Clemens entered his plea in U.S. District Court. The arraignment happened a few blocks away from where the retired pitcher swore under oath that he had not used performance-enhancing drugs.

Federal prosecutors don't believe him, and charged him with making false statements, perjury and obstruction of Congress.

Clemens says he will fight the charges.

If convicted, he could face up to 30 years in prison and a $1.5 million fine. However, a conviction could cause catastrophic damage to his reputation, future earning potential and his chances of getting into baseball's Hall of Fame.
