Scott Pruitt’s itinerary for a February trip to Israel was remarkable by any standard for an Environmental Protection Agency administrator: A stop at a controversial Jewish settlement in the West Bank. An appearance at Tel Aviv University. A hard-to-get audience with Israeli Prime Minister Benjamin Netanyahu.

One force behind Pruitt’s eclectic agenda: casino magnate and Republican megadonor Sheldon Adelson, a major supporter of Israel who arranged parts of Pruitt’s visit.

The Israel trip was canceled days before Pruitt’s planned departure, after The Washington Post revealed his penchant for first-class travel on the taxpayers’ dime. But federal documents obtained by The Post and interviews with individuals familiar with the trip reveal that it fit a pattern by Pruitt of planning foreign travel with significant help from outside interests, including lobbyists, Republican donors and conservative activists.
