Supreme Court Justice Clarence Thomas confirmed Friday he had repeatedly accepted travel from a wealthy Republican donor over more than two decades of friendship, but added that he did not have to report the gifts on annual financial disclosure forms.

Thomas has come under fire since ProPublica reported Thursday that the 74-year-old had often traveled aboard Harlan Crow’s superyacht and personal jet — even vacationing at the billionaire’s private resort in the Adirondacks.
