President Donald Trump’s nominee for the U.S. Court of Appeals for the Third Circuit downplayed his involvement in founding a conservative advocacy group in Pennsylvania during questioning before the Senate Judiciary Committee Wednesday.

Buchanan Ingersoll & Rooney shareholder David Porter—the latest of Trump’s circuit court nominees to sit for a confirmation hearing despite objections of a home-state senator—fielded questions about his political past, including whether he “co-founded” the Pennsylvania Judicial Network. The group was formed in 2009, in part to oppose Sonia Sotomayor’s nomination to the U.S. Supreme Court.
