A prominent privacy rights organization says senators must delay confirmation of Supreme Court nominee Brett Kavanaugh until after they review newly identified documents on his role establishing Bush-era surveillance programs — a request endorsed Thursday by two Democratic senators.

The Electronic Privacy Information Center sought the last-minute delay in a Wednesday night letter to Senate Majority Leader Mitch McConnell, R-Ky., and Senate Minority Leader Chuck Schumer, D-N.Y., after being told of the existence of unreleased documents held by the National Archives.
