In a statement Thursday, the National Iranian American Council accused lawmakers of attempting to undermine the Iran nuclear deal.

“It is no secret that opponents of the Iran nuclear accord continue in their attempts to upend U.S. obligations under the agreement,” the group said. “By attempting to block Boeing’s pending sale of commercial passenger aircraft to Iran, opponents of the Iran nuclear accord are also seeking to undermine significant U.S. commercial interests and to impose humanitarian suffering on the Iranian people by denying them access to safe air travel.”
