Democratic Gov. Tom Wolf's campaign held a $1,000-a-head fundraiser at the offices of a law firm that his administration and the city of Harrisburg are suing over its role in a municipal trash incinerator that helped drive the city into state receivership.

Pennlive.com reported Monday that Wolf's campaign held the June 12 fundraiser at Buchanan Ingersoll and Rooney's offices in Harrisburg.

Last month's lawsuit named four law firms, two financial entities and an engineering company in what it called it "the worst municipal financial disaster" in Pennsylvania history.

Wolf's campaign spokeswoman says the fundraiser "changes nothing" in Wolf's efforts to hold parties involved in the incinerator accountable.

A spokesman for Wolf's Republican challenger, Scott Wagner, says Wolf should refuse the law firm's contributions if he thinks it was so negligent.
