SAN FRANCISCO — A Colorado lawyer pleaded guilty to obstructing justice by leaking secret grand jury documents to two reporters covering the government's probe of steroids in sports.

Troy Ellerman agreed to be sent to prison for as long as two years and fined up to $250,000 for the convictions.

U.S. District Judge Jeffrey White isn't bound by the plea agreement and said he hasn't decided whether to accept it. White said he could impose as much as a 15-year prison term at Ellerman's sentencing, set for June 14.

The 44-year-old Ellerman, from Woodland Park, Colo., also is likely to lose his license to practice law.
