According to McNamee, Clemens first raised the subject of steroids not long after McNamee saw Canseco and Clemens meeting during the party.
Clemens' side has turned over evidence to congressional investigators, including an affidavit from Canseco, to support that the pitcher wasn't present at Canseco's home that day, the attorney, Rusty Hardin, said in a telephone interview with the Associated Press.
Hardin said video footage from telecasts of baseball games around the time of the party also were given to the House Committee on Oversight and Government Reform. During the telecasts, Hardin said, TV announcers can be heard discussing Canseco's party and noting that Clemens wasn't there.
A person familiar with the committee's investigation confirmed to the AP the affidavit and video were turned over and are in Clemens' favor.
The House panel is examining former Senate Majority Leader George Mitchell's report on drug use in baseball, and a public hearing Wednesday is expected to focus on Clemens' denials of McNamee's allegations that the pitcher used steroids and human growth hormone.
