Ethics questions follow Menendez as he plays key roles in Hill foreign, domestic policy

An ethical cloud is following Sen. Robert Menendez in Washington, even as he plays starring roles in some of Congress' most fraught domestic and foreign policy dramas. The New Jersey Democrat leads the Senate's Foreign Affairs Committee as clashes with Syria, Iran and North Korea come to the forefront. At home, the Cuban-American senator is at the center of the immigration overhaul fight that's captivating Capitol Hill. All the while, a Senate Ethics Committee investigation into Menendez's conduct persists, with many of the same questions about politics, money and influence that have dogged members of Congress through history: When does helping a supporter become a quid pro quo?
