In a defamation lawsuit filed Sunday night, Roger Clemens claims Brian McNamee, his longtime trainer and chief accuser of steroid abuse, was threatened with jail if he didn't connect the pitcher to steroids. The lawsuit was filed electronically with the Harris County civil courts Sunday evening just before CBS locally aired Clemens' interview on 60 Minutes. "I don't know if I'll ever get the naysayers back. I don't know what I'm going to get. Maybe some of my name back," a frustrated Clemens said Sunday. Clemens said this lawsuit will not keep him from testifying before Congress, which he plans to do without asking for immunity or invoking any rights. The former Houston Astro is being called to testify about McNamee's allegations that the trainer injected Clemens with steroids and human growth hormones between 1998 and 2001.
