A Houston businessman said he was given a polygraph test by the FBI concerning his relationship with Roger Clemens.

Shaun Kelley, owner of Shaun Kelley Weight Loss Centers in the Houston area, told KRIV-TV that the FBI asked him to take a polygraph test on Monday concerning his relationship with Clemens. Kelley told the station he took the exam Wednesday and is confident he passed.

"The agent looked at me and said, 'I feel real good about this, Shaun,'" Kelley said. "'I am 99.9 percent. I agree with it. I have to pass it on to quality control and then they'll make the final agreement.' He said, 'I am 99.9 percent, but I cannot give you a full agreement that it is totally true.'"

The station contacted the FBI regarding Kelley's polygraph test, but officials could not comment.

"We do not confirm nor deny investigative techniques," Special Agent and Spokeswoman for Houston Division of the FBI Shauna Dunlap told KRIV.

Kelley said he took the polygraph test at an FBI facility in Houston and the test lasted about 90 minutes. He said he was told to give yes-no answers to the questions he was asked and told the station what he considered were the two most important questions.

"They asked me if I know Roger Clemens," Kelly said. "And I said no.

"They asked me if I've ever given him human growth hormone or performance-enhancing drugs and I said no. I passed it bro, trust me."

Kelley said the FBI told him it would take 24 to 48 hours for the results of the polygraph test to become official.

The New York Times reported on March 7 that Kelley was a potential target for questioning by IRS officials looking into the sale of performance-enhancing drugs in the Houston area.

The newspaper also reported the IRS wanted to know if Kelley and Clemens had a relationship and that one of Kelley's former employees had been contacted by IRS agents asking about the two men.

Kelley said he has known all along taking a polygraph test would help clear his name.

"I've been begging to do this," Kelley said. "I've been asking to do this all along. Ever since they tried to ruin my business. All of these false accusations that have been said toward me are totally false. It's important the judicial system know this. I am going after the accusers. There will be legal action."

The Justice Department is looking into whether Clemens committed perjury after telling Congress under oath two months ago that he had never used performance-enhancing drugs. The seven-time Cy Young Award winner's former trainer, Brian McNamee, told Congress he injected Clemens a number of times from 1998-2001.
