question: Who is the doctor's attorney? answer: Matthew Menchel paragraph: Federal agents on Tuesday raided a South Florida office of Dr. Salomon Melgen, an eye doctor whose past issues with authorities had already entangled Sen. Robert Menendez. With yellow crime tape strung up outside, men and women lugged box after box of materials from Melgen's West Palm Beach office into awaiting minivans. Both members of the federal Health and Human Services department and the Federal Bureau of Investigation took part in the search, which FBI Special Agent Michael Leverock said was the second at the same Melgen clinic -- the other coming last January. "As this is part of an ongoing investigation, (authorities have) no further comment/information at this time," said Leverock. That means no official details as to what authorities were looking for. Even if it has nothing to do with his record as a generous political donor, Tuesday's raid suggests Melgen's legal troubles and perhaps their negative impact on Menendez, the senior U.S. senator from New Jersey are far from over. Confessions show sex claims were 'false smears,' senator says The doctor's lawyer contended that Tuesday's search was the government's way of getting back at Melgen, after he sued over Medicare payments. Even so, Matthew Menchel, the attorney, said that Melgen will continue to work with authorities. "While we believe that today's intrusion was in retaliation and there was no legitimate need for the search, the FBI's actions will not prevent Dr. Melgen from continuing his full cooperation with the government," Menchel said. The doctor first came to the attention of many around Washington when The Daily Caller, a conservative website, published a report shortly before the November 2012 election citing several Dominican women who claimed they'd had sex with Menendez for money. The New Jersey Democrat staunchly denied the accusation. And in March, Dominican police announced three women had been paid to claim -- falsely -- that they had sex with Menendez. While that part of the story died down, the episode raised questions about why and how Menendez admittedly flew to the Dominican Republic three times in 2010 on Melgen's private plane.
