The Senate Judiciary Committee dropped its investigation into businessman Harlan Crow on Thursday after he revealed Supreme Court Justice Clarence Thomas took three additional undisclosed trips that were not included in his revised financial disclosures.

The office of Sen. Dick Durbin (D-IL), Senate Judiciary chairman, said it obtained documents revealing previously undisclosed trips Thomas took from a subpoena to Texas-based real estate magnate Crow in November as part of an ethics investigation into the Supreme Court. Crow, who is a longtime friend of Thomas and also a GOP donor, struck a deal to give the committee seven years of information in exchange for the panel dropping its investigation into him.
