A tipster alleged to the FBI that a friend and major campaign donor to Menendez, eye doctor Salomon Melgen, made prostitutes available to the senator while they were at Melgen's home in the Dominican Republic.
Menendez acknowledged this month that he failed to properly disclose two trips he took in 2010 on Melgen's private plane to that home. The senator said he wrote Melgen a personal check for $58,500 to reimburse him for the plane rides last month. The Senate Ethics Committee is investigating the matter.
