Sen. Bob Menendez has renewed his attack on the government's corruption case against him and the Florida eye doctor he's alleged to have helped in return for cash and gifts.

Lawyers representing the New Jersey Democrat filed numerous motions in federal court late Thursday night in response to papers filed by the government last month.

Menendez and Salomon Melgen were named in a 22-count indictment this spring. Prosecutors allege Menendez accepted gifts such as trips to Paris and the Dominican Republic in exchange for using his political influence to help Melgen's business interests.

Both men have pleaded not guilty.

Their latest court filings contend Menendez was acting properly in his role as a senator and not on behalf of Melgen.

A trial is tentatively scheduled for November in New Jersey.
