Well, executive action of gun control is something the Obama White House seems to be considering in the aftermath of the horrific San Bernardino shooting that the FBI has recently reclassified as a federal terrorism investigation. Even with this development in the investigation, which renders the narrative in gun control moot–the president is looking to close the non-existent gun show loophole (via LA Times):
White House officials are seeking a way to use executive authority to close the so-called gun show loophole that allows thousands of people to buy firearms each year without a background check, but complicated legal issues have slowed the process.
Almost three years ago, after the killing of 20 children and six adults at Sandy Hook Elementary School in Newtown, Conn., President Obama asked Congress to change the law to require background checks for weapons sold outside the network of licensed gun dealers, including sales at gun shows or through the Internet. A bill to tighten the background system died in the Senate a few months later — dashing the administration’s hopes for legislative action.
