U.S. Supreme Court nominee Brett Kavanaugh was pressed Wednesday about what role, if any, the conservative Federalist Society played in his nomination.

Sen. Sheldon Whitehouse, D-Rhode Island, questioned Kavanaugh about comments White House Counsel Donald McGahn made in November that rejected the contention the White House has “outsourced” judge-picking to the Federalist Society. The group has been a major influence in the Trump White House selection of judicial nominees.
