U.S. Sen. Bob Menendez denied allegations Wednesday that he had sex with prostitutes on trips to the Dominican Republic after an FBI raid on the office of a political ally in Florida who allegedly flew him on the trips to the island nation.

The allegations, which first surfaced from a Nov. 1 report on the conservative Daily Caller website, came up again after the FBI showed up at the Palm Beach office of eye doctor Dr. Salomon Melgen. A statement from Menendez’ office released Tuesday denied the allegations.

“Dr. Melgen has been a friend and political supporter of Senator Menendez for many years. Senator Menendez has traveled on Dr. Melgen’s plane on three occasions, all of which have been paid for and reported appropriately. Any allegations of engaging with prostitutes are manufactured by a politically-motivated right-wing blog and are false,” the statement read.

FBI spokesman Jim Marshall said the agency would not comment on whether or not there was an investigation, only that they had been active in the area.

“The only information we are providing is that we are conducting law enforcement activity in the general vicinity of 2521 Metrocentre Blvd, West Palm Beach, Fla.,” Marshall said.

It is unclear what sparked the FBI search or whether it is related to Menendez, and Melgen also has financial issues. The IRS has filed a $11.1 million lien against him.

According to the Miami Herald, which first reported the raid Tuesday, FBI agents hauled away “boxes and bags of evidence” in vans from the office complex early Wednesday morning.
