On Jan. 9, Vice-President, and head of the Obama administration's task force on gun violence, Joe Biden, suggested that the President may invoke an Executive Order to limit the sale and ownership of guns in the wake of the Sandy Hook shooting. However, a little known provision passed by Congress, and signed by the President in regards to Obamacare, restricts the government from collecting any data on, or creating any databases for, guns or ammunition purchased by legal citizens.
It seems that in their haste to cram socialized medicine down the throats of the American people, then-Speaker Nancy Pelosi (D-CA) and Barack Obama overlooked Senate amendment 3276, Sec. 2716, part c.
According to reports, that amendment says the government cannot collect "any information relating to the lawful ownership or possession of a firearm or ammunition." - Breitbart
Senate amendment 3276, Sec 2716, part c was placed into the Obamacare legislation as a means to appease lobby groups such as the NRA from fighting against passage of national healthcare. Four years after its passage, this little rider in the 2800 page bill could hinder the President in what actions he can impose, or summarily enact, should he choose to follow Vice-President Biden's suggestion of issuing an Executive Order on gun control.
On Jan. 1, many parts of the Obamacare legislation became active, including the tax requirements on the American people to begin funding its later full implementation. This means that many parts of national healthcare are already being enforced, including the amendment on gun and ammunition registration. Since the Democrats no longer have control over the House of Representatives as they did in 2009 when the original bill was passed, repealing this amendment would be very difficult, as it would open up much of Obamacare to potential repeal just to remove this segment in the legislation.
As the White House continues to push for gun control measures in the wake of the Sandy Hook, and Aurora theater shootings, current legislation on the books may limit how far the President can go in implementing new restrictions on the 2nd Amendment, and the right for all citizens to bear arms. Any Executive Order issued to limit guns and ammunition, or to create a regulatory body documenting that ownership, would potentially create a legal conflict with laws already in place within the confines of Obamacare.
