The president spoke at the pro-gun rights group’s annual convention in Indianapolis and announced that he is withdrawing U.S. support for the United Nations Arms Trade Treaty, which was designed to regulate the $70 billion international arms trade. Former President Obama signed the treaty in 2013, but it was never ratified.

“Under my administration, we will never surrender American sovereignty to anyone,” Trump said as the crowd applauded. “We will never allow foreign bureaucrats to trample on your Second Amendment freedoms.”

Trump signed paperwork instructing the Senate to halt the ratification process and tossed his pen into the crowd.

The NRA and other conservative groups have long opposed the treaty, which they argued infringes on national sovereignty.
