President Donald Trump announced to pull out of an international arms treaty signed in 2013 by then-President Barack Obama but opposed by the national rifles association and other conservative groups.

Addressing the national rifle association’s annual meeting, Trump told members of the gun lobby that he intends to revoke the status of the united states as a signatory of the arms trade treaty, which was never ratified by the U.S. Senate.

The NRA has long opposed the treaty which regulates the $70 billion business in conventional arms and seeks to keep weapons out of the hands of human rights abusers. 

The lobbying group argues it would undermine domestic gun rights, a view the Obama administration rejected.

Trump added that the United Nations will soon receive formal notice of the withdrawal.

The 193-nation U.N. General Assembly overwhelmingly approved the treaty in April 2013 and the United States, the world’s no. 1 arms exporter, voted in favor of it despite fierce opposition from the NRA.

So far 101 countries have formally joined onto the treaty. Another 29, including the United States, have signed it, but not yet formally joined.
