Rosen faces two counts of making false and fraudulent statements to the Federal Election Commission for allegedly filing reports saying the event cost only about $400,000 when it really cost $1.2 million.
Prosecutors said the underreporting was designed to provide Hillary Clinton with more money for her campaign.
[Rosen] blamed the problems on event organizers Peter Paul, a three-time convicted felon who underwrote the affair, and Paul's business partner, Aaron Tonken, who is serving a five-year prison sentence for fraud.
The key here is that Rosen's doctoring of the books allowed HRC's senate campaign access to hard money (which she was chronically short of) at a critical time in the campaign.
Dick Morris pointed this out:
If the real cost of the event were $1.2 million instead of $400,000, the campaign would have had to use hard money to make up the difference. The Hillary Clinton campaign would have had $800,000 less of hard money to spend running TV ads and funding get-out-the-vote operations.
Did Hillary know? Paul and Tonken say she did, and it seems obvious that she must have: Hillary followed every dime in her campaign, personally calling donors for most of it. How could she possibly not have known of a decision that saved her $800,000?
So what we have here is really an $800,00 illegal campaign funding donation that quite possibly made HRC's victory possible.
