The amendment from Sens. Bob Menendez (D-N.J.) and Mark Kirk (R-Ill.) would toughen U.S. sanctions against Iran’s central bank in an effort to prevent the country from obtaining a nuclear weapon.
Two amendments from Sen. Dianne Feinstein (D-Calif.) are designed to change the Defense legislation’s mandate of military custody for terror suspects, an issue that’s drawn a veto threat from the White House.
It’s unclear whether Feinstein’s amendments will be successful: An attempt by Sen. Mark Udall (D-Colo.) to strip the detainee provisions from the bill was defeated Tuesday in a 38-60 vote.
