Retired baseball star Roger Clemens arrived at U.S. District Court in Washington on Monday for an arraignment on charges related to his insistence that he never used performance-enhancing drugs, according to two court officials.

Clemens, whose arraignment is scheduled for 2 p.m., faces six felony charges, including perjury, obstruction of Congress and making false statements after he told a House of Representatives committee that he never used human growth hormone or steroids.

During the arraignment, Judge Reggie Walton will make sure Clemens understands the charges and will ask him to respond with a plea. The seven-time Cy Young award winner is expected to plead not guilty.

"I never took HGH or Steroids. And I did not lie to Congress," Clemens said via his Twitter account August 19, the day a federal grand jury indicted him. "I look forward to challenging the Governments accusations, and hope people will keep an open mind until trial. I appreciate all the support I have been getting. I am happy to finally have my day in court."

The starting pitcher left baseball in 2007 after 24 seasons with major league teams, including the Boston Red Sox, Toronto Blue Jays, Houston Astros and New York Yankees. He was the first pitcher to win seven Cy Young awards.

The charges stem the pitcher's February 2008 appearance before the House Oversight and Government Affairs Committee. Both Clemens' former trainer, Brian McNamee, and a report by former Sen. George Mitchell stated Clemens had used banned substances at points in his career.

Rep. Henry Waxman, then the committee's chairman, said perjury and false statements "are serious crimes that undermine the ability of Congress to perform its duties."

"Whether he committed a crime will be up to the judge and jury," the California Democrat said in a written statement. But he said the investigation, which Waxman and then-ranking Republican Tom Davis requested, "are important actions to protect the integrity of the committee's oversight work in this area and to help end the use of steroids and performance enhancing drugs in professional sports."

During the February 2008 hearing, Clemens vehemently denied using performance-enhancing drugs.

Steroid use "is totally incompatible with who I am and what I stand for," he told lawmakers, adding, "I cannot in good conscience admit to doing something that I did not do, even if it would be easier to do so."

The six-count indictment states Clemens "did corruptly endeavor to influence, obstruct, and impede" the congressional investigation into the use of steroids by him and other major league players.

It includes three counts of making false statements to investigators about the use of human growth hormone, steroids and vitamin B12, and two counts of perjury stemming from his appearance before Waxman's committee in 2008.

That testimony put him at odds with McNamee as well as one-time Yankees teammate Andy Pettite, who told a league investigation led by Mitchell that Clemens admitted using human growth hormone. A few weeks later, the committee's leaders asked the Justice Department to launch a perjury probe of Clemens.

Clemens' lawyer, Rusty Hardin, told reporters shortly after the indictment that the pitcher expected the grand jury's decision.

"Roger has known from the very beginning that if he chose to publicly deny the accusations in the Mitchell report, that this day would come," Hardin said.

If he had used steroids, "all he had to do was just admit he did it and move on like Andy," Hardin said. But he added, "I think people will understand sometimes the government's wrong."

Clemens told investigators that Pettite -- who admitted to using human growth hormone on two occasions himself -- must have "misheard" him, and he accused McNamee of lying "to save his own skin" as federal authorities began probing the use of steroids in major sports. He filed a defamation suit against his ex-trainer in late 2008.

Clemens said the shots he received from his trainer were vitamin B12, which is an allowed substance. But according to the indictment, the trainer never had access to B12 and never injected Clemens with such supplements.
