Update from MPW: We do not know the exact charges made against Johnson. But we do know that the FBI has been investigating various people connected to the county government since at least September 2008, when it conducted a series of raids against a former County Council Member, a fire department official and a developer. Two sets of documents seized in the raids contained these labels:
DOCS FROM TOP OF RICKER'S DESK RELATED TO 5 LOTS SOLD TO J. JOHNSON.
JT VENTURE AG - STAVROU, COLTON, RICKER DEVE GRP, LLC; DRAFT LTR FROM JACK JOHNSON RE: GB SENIOR HOUSING
Also, a $700,000 charity fund set up by National Harbor developer Milt Peterson at the county's behest has attracted a bit of attention. Much of the money wound up with Johnson’s political allies. That spurred an investigation by state prosecutors in 2007. Leslie Johnson was involved in disbursing grants from the fund.
