Lawmakers are asking more and more questions about the massive ammo purchases being made by the Department of Homeland Security. For instance, a recent report says the government is on its way to amassing 1.6 billion rounds of ammunition over the next five years.

To put that into perspective, it would be enough to sustain the equivalent of the Iraq war for 24 years! The purchases have sparked conspiracy theories on the internet that the government is readying for

a domestic conflict or trying to buy up bullets as a form of gun control.

The Obama administration maintains the purchases are not out of the ordinary.

Rep. Doug LaMalfa (R-Calif.) joined Megyn Kelly this afternoon to discuss why he and other lawmakers, including Sen. Tom Coburn (R-Okla.), are looking for answers from DHS about the reasons for the purchases.

He said constituents continually complain to him about a shortage of ammunition for their personal firearms and wonder whether the government is contributing to that problem.

"It is a heck of a lot of rounds of ammunition, and for some very dubious-sounding reasons," LaMalfa noted. Megyn pressed him on what exactly is "dubious" about the government pointing out that the purchases are in bulk and meant to last a long time.

LaMalfa said for instance that the Social Security Administration has ordered about 200,000 rounds of hollow-point bullets, which have also been ordered by other federal agencies.

"(Hollow-point bullets) are not appropriate for target practice. They're much more costly rounds. ... And in this time of sequester, where everything is a disaster because of the sequester, do they really have that kind of money to be spending on this amount of ammunition?" he asked, pointing out that illegal immigrants have been released from detention due to the sequester.

LaMalfa said he's heard from local law enforcement officers who've told him that they've had problems purchasing ammo, and that DHS "is sending a wrong message" to the American people overall with this apparent buying spree.
