TOPEKA, Kan. – A Kansas congressman's 10-second naked plunge into the sea where the Bible says Jesus walked on water prompted apologies Monday from him, head-shaking from other Republicans and the kind of international attention that no politician wants.

Rep. Kevin Yoder is all but certain to keep his seat despite any embarrassment arising from last year's incident in Israel because Democrats haven't fielded a candidate against him. But the freshman Republican acknowledged many of his constituents are wondering what he was thinking when he took his "spontaneous" skinny dip in the Sea of Galilee in August 2011.

Other lawmakers on the trip also went into the water at what's considered a holy site for many Christians, and Yoder said their actions earned them a rebuke from House Majority Leader Eric Cantor. But Politico reported Sunday that Yoder was the only one who wore no clothes.
