A St. Louis congressman wants Mark McGwire's (search) name stripped off the stretch of highway that was named after Big Mac following his 70-home season in 1998.

"It would take an act by the state legislature, but I don't think he deserves a name on the highway if he can't be forthcoming about his involvement with this issue," U.S. Rep. William Lacy Clay (search), a Missouri Democrat, told The Associated Press on Friday.

McGwire refused to tell the House Government Reform Committee on Thursday whether he had used steroids. Clay is a member of that panel.

Gov. Mel Carnahan (search) signed legislation in 1999 officially naming a five-mile stretch of Interstate-70, from the city's western edge to the Illinois border, "Mark McGwire Highway."

The chairman of the state Senate Transportation Committee said McGwire's name will remain, as far as he's concerned.

"Mark McGwire was a hero of baseball in St. Louis," state Sen. Jon Dolan said. "He remains so and must deal with the choices he's made. But nothing he did would change my mind about what we do or don't name highways."

Sammy Sosa (search), Rafael Palmeiro and Frank Thomas (search) told the committee Thursday they did not use illegal steroids. McGwire has previously denied steroid use, but under oath repeatedly sidestepped questions by saying he wouldn't discuss his past.

"It was disappointing because I didn't think he took the opportunity to make clear to his fans and the rest of America that he was not under the influence of steroids when he set those home run records in 1998," Clay said. "He does not come clean. He's not forthcoming. His fans and the public want to know, where do you stand on this, Mark McGwire?"

Even Cardinals manager Tony La Russa, who managed McGwire both in Oakland and St. Louis, said he was surprised by McGwire's testimony.

"He's made a statement where he's denied it, and I thought it was a great time to make that same statement," La Russa said at spring training. "I think he was kind of coached into saying this one thing, 'I'm here about the future, not about the past.' I was surprised he didn't repeat what he said earlier. I think it would have helped his cause."
