AUSTIN, Texas (AP) ― Lance Armstrong has given sworn testimony naming several people he says knew about his performance-enhancing drug use, insisting he didn’t pay anyone or any organization to keep his doping secret.

The testimony came in written answers to questions in a lawsuit that was settled in late 2013. The previously undisclosed documents were filed this week as part of the federal whistle-blower lawsuit over his team’s sponsorship by the U.S. Postal Service that could lead to fines in excess of $100 million.

Armstrong said those who provided him with performance-enhancing drugs included trainer Pepi Marti, Dr. Pedro Celaya, Dr. Luis Garcia del Moral and Dr. Michele Ferrari, all of whom were involved with Armstrong’s teams or part of his entourage. He also said team manager Johan Bruyneel assisted his doping. Each of them has previously denied they aided Armstrong’s doping.

Armstrong also said he believed former U.S. Postal Team financier Thomas Weisel knew of his doping, which Weisel has denied.
