One new policy will end a government practice that lets military weapons, sold or donated by the U.S. to allies, be reimported into the U.S. by private entities, where some may end up on the streets. The White House said the U.S. has approved 250,000 of those guns to be reimported since 2005; under the new policy, only museums and a few other entities like the government will be eligible to reimport military-grade firearms. . .The event in the Roosevelt Room will also mark the ceremonial swearing-in for Todd Jones, whose confirmation to head the Bureau of Alcohol, Tobacco, Firearms and Explosives after six years of political wrangling to fill that position was another of Obama’s post-Newtown priorities. A Senate deal to approve the president’s pending nominations after Democrats threatened to change Senate rules cleared the way for Jones’ confirmation last month.
