The issues before Ellison are whether or not he should throw out the lawsuit and if he doesn't, whether it should stay in Texas.
"I really have been agonizing over these claims," Ellison said.
Clemens sued Brian McNamee in January after his former trainer told baseball investigator and former Senate Majority Leader George Mitchell that the seven-time Cy Young Award winner used steroids and human growth hormone.
Clemens, a 354-game winner, is under investigation by the FBI after denying McNamee's claims while under oath during a deposition and public testimony before a congressional committee.
Richard Emery, one of McNamee's attorneys, said the lawsuit should be dismissed on the grounds that his client's statements to Mitchell were protected by privilege through a deal McNamee struck with federal prosecutors.
Emery also argued the lawsuit should not stay in Texas because many of the allegations McNamee made against Clemens relate to things that happened in Toronto, Florida and New York. McNamee's attorneys want the case moved to New York, where he lives. Clemens lives in Houston.
"The only person who ruined Roger Clemens' life is Roger Clemens by not admitting the truth," Emery said.
But Clemens' attorneys argued McNamee's statements are not protected because he made them to a private individual, Mitchell, who was part of a private investigation and that they were not part of a judicial proceeding or a federal probe.
Mitchell was hired by Major League Baseball commissioner Bud Selig to examine steroid use in baseball.
"You do not get to trash somebody's name without having to pay a price," said Joe Roden, one of Clemens' attorneys.
Roden also said the lawsuit should stay in Texas because McNamee did business in Texas and because McNamee's statements against Clemens have done him the most harm in Texas.
Ellison called the issue about whether McNamee's statements were part of a government investigation and therefore privileged the possible "lynchpin of the whole case."
The judge gave no timeline about when he would issue a ruling in the case.
Clemens originally filed the suit in Texas state court, but McNamee had it removed to the federal system.
