Rajaratnam Attorney: 'This is My Last Trial'

No matter how the insider trading trial of hedge fund mogul Raj Rajaratnam turns out, his lead attorney tells CNBC exclusively that it will be his last trial.

"It's a young man's game," said John Dowd, 70, after the first day of closing arguments in the six-week trial.

Dowd, a partner at the Washington law firm Akin Gump Strauss Hauer & Feld, is a highly regarded white collar defense attorney, perhaps best known for his investigation of gambling by baseball's Pete Rose.

Asked if he decided before or after the Rajaratnam case began to make this his last trial, Dowd laughed and said, "Well, after I got into it."

Dowd delivered about an hour of his closing argument on Wednesday, attacking the government's cooperating witnesses as "liars" and the prosecution's case as "a fiction."

Dowd told CNBC that while he is "tired," he feels good about the defense case, and that his client, Rajaratnam, is "a rock."
