Supreme Court nominee Brett Kavanaugh suggested several years ago that the unanimous high court ruling in 1974 that forced President Richard Nixon to turn over the Watergate tapes, leading to the end of his presidency, may have been wrongly decided.

Kavanaugh was taking part in a roundtable discussion with other lawyers when he said at three different points that the decision in U.S. v. Nixon, which marked limits on a president’s ability to withhold information needed for a criminal prosecution, may have come out the wrong way.

A 1999 magazine article about the roundtable was part of thousands of pages of documents that Kavanaugh has provided to the Senate Judiciary Committee as part of the confirmation process. The committee released the documents on Saturday.
