Charles Schumer, D-N.Y., left, announce with other senators that they have reached agreement on the principles of sweeping legislation to rewrite the nation's immigration laws, during a news conference at the Capitol in Washington. Menendez said Monday, Feb. 4, 2013, that allegations that he engaged with prostitutes in the Dominican Republic are false "smears." He said he has done nothing wrong and that allegations otherwise are "totally unsubstantiated." (AP Photo/J. Scott Applewhite, File)

But the senator denies he sought to intervene improperly in billing disputes between the doctor and the government.
Menendez, a New Jersey Democrat, says Thursday he contacted the Centers for Medicare & Medicaid Services to ask about billing practices. This was during a dispute between CMS and Salomon Melgen, a longtime friend and donor. The FBI searched Melgen’s Florida offices last week.
Menendez says, “The bottom line is, we raised concerns with CMS over policy and over ambiguities that are difficult for medical providers to understand, and to seek a clarification.”
