An effort to bar the US Defense Department from selling surplus parts for the F-14 fighter jet - a plane now flown only by Iran - has gained support in the House of Representatives.
A Democrat said Thursday she will make it her first proposal as a congresswoman.
Rep. Gabrielle Giffords, a member of the House Armed Services Committee, called her bill "a common-sense piece of legislation."
"I don't believe most Americans are aware of the fact that the Iranians do have a fleet of F-14s and that we sold them to them," Giffords said. "I hope that this legislation is just one step in what will be many to be able to keep better control over our equipment and to make sure that we are not helping to militarize the Iranians."
