WASHINGTON (AP) — Roger Clemens has been acquitted on all charges by a jury that decided he didn't lie to Congress when he denied using performance-enhancing drugs.

Jurors returned their verdict Monday after close to 10 hours of deliberation. The outcome brings an end to a 10-week trial that capped an expensive, five-year investigation into one of the greatest pitchers in the history of baseball.

The 49-year-old Clemens was accused of perjury, making false statements and obstructing Congress when he testified at a deposition and at a nationally-televised hearing in February 2008. The charges centered on his repeated denials that he used steroids and human growth hormone during his 24-year career.
