Obama Looking For Ways Around Congress On Gun Policy
Faced with a Congress hostile to even slight restrictions of Second Amendment rights, the Obama administration is exploring potential changes to gun laws that can be secured strictly through executive action, administration officials say.
The Department of Justice held the first in what is expected to be a series of meetings on Tuesday afternoon with a group of stakeholders in the ongoing gun-policy debates. Before the meeting, officials said part of the discussion was expected to center around the White House's options for shaping policy on its own or through its adjoining agencies and departments -- on issues ranging from beefing up background checks to encouraging better data-sharing.
Administration officials said talk of executive orders or agency action are among a host of options that President Barack Obama and his advisers are considering. “The purpose of these discussions is to be a productive exchange of good ideas from folks across the spectrum,” one official said. “We think that’s a good place to start.”
For gun control advocates, however, executive action remains a more promising -- albeit more limited -- vehicle for reform than Congress. On Monday, The Huffington Post first reported that the Justice Department was convening meetings with groups from across the ideological spectrum in an effort to chart potential policy changes to Second Amendment law.
The discussions were meant to build a broad coalition around the elements of reform Obama had outlined a day earlier in an op-ed for the Arizona Daily Star, including stronger state-to-state coordination, expedited background checks and greater enforcement of the laws already on the books, especially with regard to the National Instant Criminal Background Check System.
The extent to which Obama can change gun law without the hand of Congress is not, gun control activists say, wholly insignificant. Though they say they'd prefer longer-lasting, broader legislative responses to shootings like that which occurred in Tucson, Ariz., in early January, there are notable gaps that can be filled with presidential action.
With respect to the shooting of Rep. Gabrielle Giffords (D-Ariz.), a Clinton-era rule had prevented the military from reporting to the Federal Bureau of Investigation that the alleged shooter, Jared Loughner, had been rejected as a recruit for failing a drug test. Obama could reverse that without Congress, Glaze and an administration official said.
As for other possible actions that can be taken without Congress, Mayors Against Illegal Guns has compiled a wishlist of sorts, suggesting that the national background-check system enforce the requirement that all federal agencies report individuals forbidden under federal law from purchasing guns; that the White House restructure regulations requiring that the FBI destroy firearm-purchase records after 90 days; that the FBI, DOJ and the Bureau of Alcohol, Tobacco, Firearms and Explosives be more aggressive in pursuing federal prosecutions against those individuals who illegally attempted to buy firearms; and that the latter agency ramp up undercover investigations of sales at gun shows.
