This isn't the only time, of course, that investigators haven't been told the truth about Griles' dalliances. Griles and his current girlfriend, Sue Ellen Wooldridge, successfully kept their relationship from the department's Inspector General when he was investigating Griles for lobbying for his old clients on the inside -- at the time, Woolrdige, then Norton's deputy chief of staff, had been charged with watching over Griles. But she didn't tell the IG about the relationship.
Griles and Woolridge hit the papers last month because the pair bought a vacation home with an oil lobbyist -- even though Woolridge at the time worked as the Justice Department's top environmental prosecutor.
Update: So here are the terms of the plea, just out from the Justice Department: Griles faces a maximum sentence of five years in prison and a $250,000 fine. He's pled guilty to obstruction of justice.
The AP has reported that "federal prosecutors will seek no more than a 10-month prison sentence for Griles - the minimum they could seek under sentencing guidelines - but they will agree to let him serve half that in home confinement."
Update: Here's the "factual basis" for Griles' plea, a document that goes into more detail about the case.
