If Jason Giambi decides not to speak to George Mitchell, he could face a different set of questioners - a Congressional committee. Mitchell, the former Senate Majority Leader, has told baseball owners that Congress - which has subpoena power, unlike him - may get involved if players do not cooperate with his probe. Yesterday, one congressman said it?s time for another hearing. Rep. Cliff Stearns (R-FL), who held hearings on steroid use in baseball in 2005, is no longer the chairman of the Commerce, Trace & Consumer Protection Subcommittee but said he thinks another hearing is in order. ?I believe that our oversight on this issue, along with my legislation, were factors in Major League Baseball adopting a stricter steroid-use policy,? Stearns said in a statement. ?In light of recent disclosures of steroid use in baseball, it obviously still remains a problem in MLB. I believe that another hearing on the subject could again produce meaningful results, and I hope that the new chairman will take this step.?
