President Obama’s nuclear deal with Iran might be making it easier for the rogue regime to fly weapons into Syria, a group of Republican senators warned.

Obama’s team agreed to allow major airplane manufacturers to sell almost 200 airplanes to Iran Air, an airline that had been under sanction for transporting weapons on behalf of terrorists. The company may still be doing so, given that Iran Air planes are flying the supply routes used to send military supplies to Syrian dictator Bashar Assad. But it’s also possible that other Iranian airlines that remain sanctioned will use the planes to transport weapons.
