Washington ? Under oath and sometimes blistering questioning, Roger Clemens stuck to his story Wednesday. So did his chief accuser and former personal trainer, Brian McNamee.

And after a 41â2-hour hearing, Congress settled for a draw in the he-said, he-said between the two men over whether the seven-time Cy Young Award winner used performance-enhancing drugs. Ultimately, the matter may be referred to the Justice Department for a resolution – and, possibly, criminal charges.

“I haven’t reached any conclusions at this point,” said California Democrat Henry Waxman, chairman of the House Oversight and Government Reform Committee.

But, as ranking Republican Tom Davis of Virginia, put it: “Both can’t be telling the truth.”

Clemens and McNamee, once employer and employee, and by all accounts once friends, sat at the same witness table and rarely, if ever, looked at the other.

His reputation and legacy on the line, Clemens gestured toward McNamee with his right arm and said, “I have strong disagreements with what this man says about me.”

At times, Clemens struggled to find the right words as he was pressed by lawmakers about McNamee’s allegations – told to federal prosecutors and then baseball investigator George Mitchell – that he injected the pitcher with steroids and human growth hormone from 1998 to 2001. Clemens also was asked about new accounts of drug use made against him by former teammate and pal Andy Pettitte.

Using words like “misremembered” and even mispronouncing McNamee’s name at one point, Clemens raised his voice toward the end to interrupt Waxman’s closing remarks. Waxman pounded his gavel and said, “Excuse me, but this is not your time to argue with me.”

It seemed clear nearly from the start that the committee would not treat Clemens with kid gloves, despite all the face-to-face sit-downs he did with representatives in recent days – sometimes posing for photos or signing autographs for staff members.

Later, the committee appeared split along party lines, with the Democrats reserving their most pointed queries for Clemens, and the Republicans giving McNamee a rougher time. Chris Shays, a Connecticut Republican, likened the hearing to a “Roman Circus” featuring gladiators.

“I have never taken steroids or HGH,” Clemens said after rising with McNamee to swear to tell the truth. “No matter what we discuss here today, I am never going to have my name restored.”

For many, his denials rang hollow.

“It’s hard to believe you, sir,” said Rep. Elijah Cummings, a Maryland Democrat. “I hate to say that. You’re one of my heroes. But it’s hard to believe.”

McNamee’s answers were generally quick and concise. His credibility also came under scrutiny.

“You’re here under oath, and yet we have lie after lie after lie after lie,” said Rep. Dan Burton, an Indiana Republican.
