The Senate bill, if it becomes law, would direct the White House to press SWIFT to drop Iranian banks, and would give the Treasury Department the power to sanction SWIFT and the banks that own it.
On Thursday, Ileana Ros-Lehtinen, the Republican chairwoman of the House Foreign Affairs Committee, introduced a companion bill that would bar SWIFT from providing services to Iran, or face sanctions.
U.S. lawmakers are pressing forward on a sanctions package that they hope to further hurt revenues they say Tehran is using to develop nuclear weapons. Iran denies seeking nuclear arms.
