The Young Turks look into the story of Rep. Kevin Yoder skinny dipping in the Sea of Galilee while on an AIPAC junket to Israel.  I think Richard Silverstein nails this story:

It would be unfortunate if Aipac came out of this smelling like a rose.  It certainly knew of the misbehavior.  One wonders what other sorts of behavior have occurred on Israel junkets and whether there has been creative accounting used on other trips.  The main point is that these trips and those who sponsor them and even those who participate in them are engaging in corrupt acts.  I don’t mean this legally since unfortunately these junkets aren’t illegal (though they should be).  I mean, rather, that the trips, the enormous amounts spent on them, the wining and dining, the influence peddling–all of it is corrupt.  It nourishes the dysfunction which characterizes the Congressional approach to Israel issues.
