Apparently they were simply attempting to walk home. From Politico.com:
The FBI probed a late-night swim in the Sea of Galilee that involved drinking, numerous GOP freshmen lawmakers, top leadership staff – and one nude member of Congress, according to more than a dozen sources, including eyewitnesses.
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 [said]. 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 took part in the trip.

These GOP sources confirmed the following freshmen lawmakers also went swimming that night: Rep. Steve Southerland (R-Fla.) and his daughter; Rep. Tom Reed (R-N.Y.) and his wife; Reps. Ben Quayle (R-Ariz.), Jeff Denham (R-Calif.) and Michael Grimm (R-N.Y.).
Many of the lawmakers who ventured into the ocean said they did so because of the religious significance of the waters. Others said they were simply cooling off after a long day. Several privately admitted that alcohol may have played a role in why some of those present decided to jump in.
This could have implications at least for Quayle, the son of the former vice president. Ben Quayle has significant primary opposition for his Arizona seat from Dave Schweikert, a tea party-backed candidate.
