WASHINGTON AP – Former Deputy Interior Secretary J. Steven Griles pleaded guilty Friday to obstruction of justice, becoming the ninth person and the highest-ranking Bush administration official convicted in the Jack Abramoff lobbying scandal.

The former No. 2 official in the Interior Department admitted in federal court that he lied to Senate investigators about his relationship with convicted lobbyist Abramoff, who repeatedly sought Griles’ intervention at the agency on behalf of Abramoff’s Indian tribal clients.
