WASHINGTON - Bud Selig and Donald Fehr, the commissioner and union leader often at loggerheads, sat side-by-side Tuesday as the U.S. Congress pressed them yet again with questions about baseball's doping problem.

At a House Oversight and Government Reform Committee hearing in the same, wood-panelled room where Selig, Fehr, Mark McGwire, Rafael Palmeiro and others testified three years ago, congressmen mixed criticism of baseball and its players with praise for progress on steroids.

That 2005 hearing was referenced right away when panel chairman Henry Waxman opened the proceedings by calling on the Justice Department to look into whether former AL MVP Miguel Tejada lied to committee staffers when questioned in connection to Palmeiro's perjury case.

Waxman then turned the focus to former Senate majority leader George Mitchell's report on baseball's steroids era.

"The illegal use of steroids and performance-enhancing drugs was pervasive for more than a decade, Major League Baseball was slow and ineffective in responding to the scandal, and the use of human growth hormone has been rising,'' said committee chairman Henry Waxman, a California Democrat.

"The Mitchell Report also makes it clear that everyone in baseball is responsible: the owners, the commissioner, the union and the players.''

After Mitchell's two-hour appearance, Selig and Fehr went before the panel. Maryland Democrat Elijah Cummings said to Selig and Fehr: "This scandal happened under your watch. I want that to sink in. It did. Do you accept responsibility for this scandal or do you think there was nothing you could do to prevent it?''

Fehr paused for several seconds.

"Did we or did I appreciate the depth of the problem? ... The answer is `No,''' Fehr replied. "It's a failure that we didn't and it's a failure that I didn't.''

Selig then followed, starting by saying he's agonized over the question.

"Do I wish we could have reacted quicker? Should we have? One could make the case,'' the commissioner said. "All of us have to take responsibility, starting with me.''

In his opening statement, Selig vowed to develop a program "to require top prospects for the major league draft to submit to drug testing before the (amateur) draft.'' He also reiterated his willingness to support use of a test for human growth hormone "when a valid, commercially available and practical test for HGH becomes reality, regardless of whether the test is based on blood or urine.''

Fehr, in turn, said the union has agreed to "allow players to be suspended for HGH use based on evidence other than a positive test, a so-called `non-analytical' finding.''

He and Selig said they met in December to discuss the Mitchell Report's investigations and plan to meet again.

"I hope we have all of this completed before spring training,'' Selig said.
