Sent 3: 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.
Sent 4: "As this is part of an ongoing investigation, (authorities have) no further comment/information at this time," said Leverock.

Sent 8: Even so, Matthew Menchel, the attorney, said that Melgen will continue to work with authorities.
Sent 9: "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.
Sent 10: 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.
Sent 11: The New Jersey Democrat staunchly denied the accusation.
Sent 12: And in March, Dominican police announced three women had been paid to claim -- falsely -- that they had sex with Menendez.
Sent 13: 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.
Question: What information came out in March? Were there any questions left? (A) Menendez had sex with 3 women, yes (B) Nothing, no (C) Three women were paid to false claim they had sex with Menendez. The question that remained was why Menendez traveled to the Dominican Republic three times.
