In a shocking turnaround, the U.S. Justice Department has dropped its case against Sen. Robert Menendez. In a court hearing in Newark today, federal prosecutors moved to dismiss the corruption indictment against the New Jersey Democrat. Last week, a federal judge had acquitted Menendez and his co-defendant, Salomon Melgen, of seven of the 18 counts against them after a deadlocked jury could not reach a verdict in the high-profile case in November.
