NJ.com reported, "The court, as is custom, gave no reason for deciding not to hear the appeal from the Third Circuit Court of Appeals in Philadelphia, which in July ruled that the case should go to trial.
Menendez (D-N.J.) who is up for re-election next year, is accused of intervening with federal agencies on behalf a friend and campaign donor, Dr. Salomon Melgen, in exchange for gifts and contributions."
The indictment alleges that Menendez intervened in a dispute between Medicare and Melgen at Melgen's request, and also with a contract in the Dominican Republic involving one of Melgen's companies. Melgen is an eye doctor in Florida.
U.S. District Judge William H. Walls ruled in 2015 that the trial should go forward.
Abbe Lowell, Menendez's lawyer, was quoted as saying, ""It's disappointing that the Supreme Court did not take this opportunity to set a clear, bright line of the separation of powers to ensure that Congress remains an independent and co-equal branch of government, free of interference and retribution from the executive as the framers intended."
An indictment is not a judgment of guilt or innocence. It's a decision that there's enough evidence to bring a case to trial.
