Last night, the Green Party of Pennsylvania's Steering Committee voted to demand an investigation of the Democratic and Republican Party's activities since 2004. In a letter to State Attorney General Tom Corbett, the Green Party called for an immediate probe into the bonuses paid to legislative staffers for their work on behalf of candidates and for legal charges to be filed, if warranted. They also asked that the investigation cover 2006 activities, which did not initially seem to be the subject of concern.
