WASHINGTON - The White House is opposing a House bill that aims to block implementation of the Iran nuclear deal until Tehran pays billions of dollars in damages to victims of Iranian-sponsored terror.

In a statement on Wednesday, the Obama administration said the bill, which the House is to vote on Thursday, would undermine U.S. national security interests.

The bill, written by Pennsylvania Republican Rep. Patrick Meehan, would prohibit the president from lifting sanctions on Iran until it pays some $43 billion in damages that U.S. courts have awarded to victims of the attacks. The bill has more than 100 co-sponsors in the House.

House lawmakers are to join victims of Iranian-sponsored terror on the House Triangle later in the day to urge passage of the bill.
