"During a fact-finding congressional trip to the Holy Land last summer, Rep. Kevin Yoder (R-Kan.) took off his clothes and jumped into the sea, joining a number of members, their families and GOP staff during a night out in Israel, the sources told POLITICO. Other participants, including the daughter of another congressman, swam fully clothed, while some lawmakers partially disrobed. More than 20 people took part in the late-night dip in the sea, according to sources who were participants in the trip."
This was covered on the TODAY show this morning. Not sure if the other networks picked it up. They seemed to emphasize that these people went swimming - and skinny dipping! - in the holy body of water. i.e. These people were doing something wrong just by swimming in the Sea. A very brief Google search shows that the Sea of Galilee is a tourist destination with many beaches, resorts, etc.
