Baseball star Roger Clemens has filed a defamation suit against his former trainer Brian McNamee. The complaint can be found here.

According to last month’s “Mitchell Report" on illegal steroid use in baseball, McNamee told investigators that he had injected Clemens with illegal steroids.

Both men, along with some other individuals connected to the report, are scheduled to testify before the U.S. House of Representatives Committee on Oversight and Government Reform.
