If both parties signed non-disclosure agreements and private money was used for payoffs, is there any way to know about those settlements? Other than asking every member of the House and Senate if he/she has ever been a party to one.
But private money was allegedly NOT used for the payoffs, it was taxpayer money and that makes it illegal as all hell. Worse than the check kiting bank they used to have.
Even if other parties were silenced, wird gets out. People know.
