All is not quiet in the southern front, as the Obama administration's plan to force new reporting requirements on thousands of gun dealers near the Mexico border is under fire from members of his own party.

At least three Democrats in the Senate and several more in the House are voicing opposition to a proposed regulation from the Bureau of Alcohol, Tobacco, Firearms and Explosives that would require about 8,500 gun dealers in four states – California, New Mexico, Arizona and Texas – to report gun sales of two or more high-powered rifles sold within five consecutive business days.

The proposal isn't connected in any way to the mass shooting in Arizona last weekend that left six people dead and 14 others wounded, including Rep. Gabrielle Giffords, D-Ariz., because the suspect used a handgun, which is already covered under these reporting requirements.

The new regulation would cover semiautomatic rifles greater than .22 caliber with detachable magazines.

Sen. Mark Begich, D-Alaska, has asked the ATF to withdraw its request to the White House for emergency authority to enact the regulation.
