The United States Senate voted unanimously this evening (100-0) to defy the Obama Administration and impose sanctions on the Iranian Central Bank.

The administration had lobbied against the sanctions, arguing they could somehow jeopardize American relations with allies and fund Iran’s nuclear program. Exactly how the sanctions would so isn’t clear.

In fact, the sanctions specifically target funding for the country’s nuclear program and follow similar sanctions imposed by European nations and our staunch ally the United Kingdom.

“The sanctions would prohibit financial institutions that do business with the bank of Iran from opening or maintaining correspondent banking accounts in the United States,” explained the office of one of the bill’s sponsors, Sen. Robert Menendez, D-N.J., in a press release announcing the vote results. “If we are serious about stopping Iran from obtaining a nuclear weapon, we must be willing to follow the money that feeds its nuclear ambitions and to take real action against the Central Bank of Iran, starving the regime of the resources it needs to advance its terrorist agenda,” Menendez said in a statement.

Just the latest blow to an increasingly unpopular administration with ever-decreasing political capital.
