From Texas Standard:
During President Obama's Oval Office speech on Sunday evening, he laid out two gun control measures he wanted Congress to act on, one of them dealt with the nation's no-fly list.
"To begin with, Congress would have to make sure no one who's on a no-fly list would be able to buy a gun," Obama said in his televised address. "What could possibly be the argument for allowing a terrorist suspect to buy a semi-automatic weapon? This is a matter of national security."
But many, including the ACLU, have concerns about tying the no-fly list to a database for firearm purchases.
