There may be more to the story I wrote about earlier today, specifically the fact that one of the (non-nude) Congressman is apparently the target of an FBI investigation:

Law enforcement sources — noting that skinny-dipping usually doesn’t fall under the FBI’s purview — pointed TPM to a New York Times story from earlier this month about a trip to Cyprus that Rep. Michael Grimm (R-NY) made following his August venture to Israel alongside several colleagues.

Politico, which first reported the skinny-dipping anecdote, said the FBI “looked into whether any inappropriate behavior occurred, but the interviews do not appear to have resulted in any formal allegations of wrongdoing.”

But FBI agents were actually interested in Grimm’s failure to file paperwork related to his trip to Cyprus following his Israeli junket, which had been paid for by the Cyprus Federation of America. The president of that company was arrested on federal corruption charges in June. Grimm had reported the Israel trip in his initial filing in May but did not list the trip to Cyprus until he amended it in June, one day after Cyprus Federation of America’s president was arrested.

FBI agents may have asked questions about “who went into the water that night, and whether there was any impropriety,” as Politico reported, but sources indicated the dip in the water certainly wasn’t the FBI’s central focus.

Grimm, a former FBI agent, has been the subject of plenty of attention from federal authorities over the past year. On Friday, one of Grimm’s top fundraisers was arrested for allegedly lying about the source of a loan on immigration documents. That man, an Israeli named Ofer Biton, traveled around the New York area with Grimm in 2010 to raise money for his congressional campaign. At least four of Grimm’s 2010 campaign workers have been questioned by the FBI. Federal prosecutors have also interviewed several donors, according to the New York Times.

Stay tuned…..
