Roger Clemens was found not guilty on all charges on Monday afternoon.
Clemens was charged with one count of obstruction of Congress, three counts of making false statements and two counts of perjury.
He was accused of lying to Congress during an investigation into steroid use among baseball players.
The decision comes after a two-month trial that centered on Clemens telling Congress that he never used steroids, despite multiple witnesses testifying to the opposite effect.
He faced a maximum sentence of 30 years in prison and a $1.5 million fine if convicted on all six counts.
