WWW- DID New Jersey Sen. Robert Menendez share a secret Hoboken love nest with a former aide with whom he was rumored to be having an affair?

A search of Menendez on several person-locator Web sites shows that after he moved out of the Union City, N.J., house he shared with his then-wife, Jane, in 2003, Menendez gave his address as 1 Independence Court in Hoboken for a brief time.

That same Hoboken address also appeared on a search of Kay LiCausi, Menendez's former chief of staff with whom staffers to former Gov. James McGreevey claimed he was having a long-term affair.

Menendez, who's now divorced, and LiCausi have repeatedly refused to confirm or deny whether they were ever romantically linked. Menendez spokesman Matthew Miller said such Internet search sites are not always accurate. But Miller could not explain how two people so closely tied ended up on the sites having lived at the same address.

Miller insisted the Democratic senator never lived at the Independence Court apartment, never used it as an alternate address and had nothing mailed there. But when asked if Menendez had ever spent time at the apartment, Miller refused to comment.

"These databases are known to produce errors, and this is no exception," Miller told the Post's Kenneth Lovett.

He said Menendez lived with his wife at their Union City house until they separated in February 2003. At that point, Miller said, Menendez moved into an apartment on Clinton Street in Hoboken. He provided copies of the leases as proof.

"He has lived in that apartment since then and nowhere else, except for an apartment he stays in when he is in Washington," Miller said.

Menendez, 52, was found to have helped steer at least $200,000 worth of business to LiCausi after she left his employ to become a lobbyist and political consultant.

McGreevey aides leaked news of the alleged affair after Menendez called for the governor's immediate resignation after he admitted to a gay relationship with an aide in 2004. Menendez was tapped by Gov. Jon Corzine to replace him in the Senate in January and is now in a tough campaign against Republican Tom Keane Jr.
