WASHINGTON, DC (WUSA9) -- It's been exactly a week now since Jeff Thompson told a judge the Mayor not only knew about the illegal campaign money, but that he actually solicited it.
So here is what we know so far about the potential case against the Mayor.
Federal rules circumscribe what prosecutors can talk about, but US Attorney Ron Machen has detailed what he could at a news conference. "Jeff Thompson believed that supporting Mayoral Candidate A would improve the business climate for DC Chartered, one of his companies that had a $300 million dollar contract with the city," he said.
Thompson, who owned DC Chartered Health, pleaded guilty a week ago to conspiring to corrupt local and federal campaigns with more than $3 million in illegal funding.
Under Mayor Fenty, Chartered had to pay back the city $12 million in over-payments. Under Mayor Gray the city paid Chartered an extra $7.7 million, to settle another dispute.
The prosecutor says Thompson told Gray that if he ran for Mayor against Fenty, he'd help finance his campaign. And he says two of Gray's aides, who have pleaded guilty, took nearly $100,000. But when they came back for much more money, Thompson says he insisted the Mayor ask for the money himself.
"During that meeting," said Machen, "the candidate handed Thompson a one page budget listing $425,000 in get out the vote expenses. The candidate asked Thompson to fund the budget."
Machen's investigation has led eight people so far to accept guilty pleas... And he's not finished. "If you participated in backroom under the table deals with Jeff Thompson, I urge you to come forward now and own up to your conduct. I promise you, we're not going away."
Not going away until he roots out corruption he says has plagued the city for years.
The prosecutor says he's pushing the investigation as quickly as he can. But he says he has no artificial timetable to finish.
