Reid Weingarten and Brian Heberlig of Steptoe & Johnson had four boxes full of evidence meant to destroy the credibility of Pennsylvania’s former treasurer on the witness stand.

Rob McCord—a disgraced politician who admitted to extorting campaign contributions from donors, and who agreed to testify against their client for leniency—was the prosecution’s star witness against 80-year-old Chester County business man Richard Ireland. According to prosecutors, Ireland funneled $500,000 in “secret” campaign donations to McCord in 2008 in exchange for his investment of millions in state money into Ireland’s business.
