He is charged with one count of obstruction of Congress, three counts of making false statements and two counts of perjury, according to federal officials. The charges stem from his February 2008 testimony before the House Committee on Oversight and Government Reform.
Clemens, 48, faces a combined maximum sentence of 30 years in prison and a $1.5 million fine, but under the advisory U.S. Sentencing Guidelines, the range of imprisonment is presently 15-21 months, said the U.S. Attorney's office for the District of Columbia.
Update: One of the lawyers representing Clemens during his testimony before the committee was Lanny Breuer, who now serves as Assistant Attorney General for the Criminal Division.
Breuer, shown seated behind Clemens in the photo accompanying this story, squared off with Rep. Henry Waxman during the hearing in question, as seen in the video below.
