The former Democratic congressman has argued that prosecutors trampled on his constitutional privileges as a lawmaker. But the high court refused to hear Jefferson's appeal to throw out the indictment against him.

Jefferson was indicted in 2007 on multiple counts, including soliciting bribes and racketeering. Investigators raided Jefferson's home and found $90,000 in cash stuffed in a freezer.

A federal judge has set a June 2 trial date in Alexandria, Va.

Jefferson represented parts of New Orleans in Congress, but lost his re-election last year to Republican Rep. Anh "Joseph" Cao.

Last year, a three-judge panel of the 4th U.S. Circuit Court of Appeals in Richmond, Va., rejected Jefferson's claims that a federal grand jury received evidence that violated his constitutional right to legislative immunity.
