PORKBUSTERS UPDATE: Here’s more on that Murtha earmark scandal:

More than 100 House members secured earmarks in a major spending bill for clients of a single lobbying firm — The PMA Group — known for its close ties to John P. Murtha , the congressman in charge of Pentagon appropriations.

“It shows you how good they were,” said Keith Ashdown, chief investigator at the watchdog group Taxpayers for Common Sense. “The sheer coordination of that would take an army to finish.”

PMA’s offices have been raided, and the firm closed its political action committee last week amid reports that the FBI is investigating possibly illegal campaign contributions to Murtha and other lawmakers. . . . In the spending bill managed by Murtha, the fiscal 2008 Defense appropriation, 104 House members got earmarks for projects sought by PMA clients, according to Congressional Quarterly’s analysis of a database constructed by Ashdown’s group.

Those House members, plus a handful of senators, combined to route nearly $300 million in public money to clients of PMA through that one law (PL 110-116).

And when the lawmakers were in need — as they all are to finance their campaigns — PMA came through for them.

Stay tuned.
