Obama puts off signing the UN Arms Trade Treaty

Kerry, however, said the administration still has concerns that the U.N.'s various translations of the pact don't include the same language.
“The United States welcomes the opening of the Arms Trade Treaty for signature,” Kerry said in a statement. “We look forward to signing it as soon as the process of conforming the official translations is completed satisfactorily.”
The NRA insists the pact is a U.N.-backed gun grab. A majority of senators have already said they oppose the treaty, making ratification impossible in the short-term.
Kerry pushed back against those concerns, saying the treaty would in no way infringe on Second Amendment rights.
