Potential Pennsylvania Senate challenger Pat Toomey, president of Club for Growth and a former Republican congressman, responded today to Sen. Arlen Specter's (R-Pa.) TV ad and request for Toomey to disclose any contributors to his conservative group that had received TARP funds.

FactCheck.org analyzed Specter's ad last week and noted that it "misfires a few times." As the Pittsburgh Post-Gazette reported, Specter was forced to change the wording of the ad -- it accused Toomey of selling credit default swaps, though such swaps had not yet been invented when Toomey worked on Wall Street during the 1980s.

Specter also sent a letter requesting the Club for Growth "disclose any contributors that had received federal funds under the controversial financial bailout legislation enacted in October," the Post-Gazette reported. A Toomey press release responds to the request, claiming "Specter has taken more money from AIG, Citigroup, Goldman Sachs, and J.P. Morgan Chase and other financial services companies than any other Pennsylvania member of congress in the last twenty years (Center for Responsive Politics)."

Toomey spokesman Mark Harris responds in a press release:

"Arlen Specter's bad poll numbers must be causing him hallucinations. Everything he attacks Pat Toomey with is either proven false by neutral analysts, or is something Specter himself has done. There isn't enough mud left in Pennsylvania for Specter to cover up the fact that he voted to spend billions of tax dollars to bail out Wall Street. He has pocketed millions from Wall Street firms, while Pat Toomey strongly opposes these bailouts."
