To bolster McNamee's credibility, the government hopes to win an argument to include previously barred evidence that shows McNamee supplied drugs to other players who have since acknowledged that they were users. Hardin claimed that would open up a "bunch of minitrials" over each player associated with McNamee and could extend the trial for months.
The judge said he will rule on the matter Monday morning.
Late Friday afternoon, the House Oversight and Government Reform Committee and its chairman, Rep. Darrell Issa, filed a motion to quash Clemens' subpoenas for Issa's testimony and committee documents. That committee held the hearing that Clemens testified before in 2008; Issa, a California Republican, was not chairman at the time.
The motion argues that the subpoenas are barred by the Constitution's speech or debate clause, which protects elected officials from being questioned in a lawsuit about their legislative work.
"In particular, the subpoena to Chairman Issa should be quashed because high-ranking government officials may not be compelled to testify absent extraordinary circumstances, including that the official is uniquely able to offer that testimony, unlike here," the House general counsel's office said in its motion.
