The Trump administration on Friday cited a national security emergency" allegedly caused by Iran to bypass Congress and rush through arms sales worth billions of dollars to Saudi Arabia and other Middle East allies, in a move that drew condemnation from lawmakers on both sides of the aisle. Citing a rarely used provision of arms control law, the administration informed lawmakers it was declaring a national security emergency, allowing it to go ahead with the sale of weapons to Saudi Arabia, the United Arab Emirates and Jordan without congressional approval, according to administration letters sent to senators. The decision affected various arms packages worth roughly $8 billion. The move came despite growing bipartisan opposition to any arms sales to Saudi Arabia amid outrage over the killing of Saudi writer Jamal Khashoggi at the Saudi consulate in Istanbul last year, as well as over Riyadh's air war in Yemen that has caused high numbers of civilian casualties. A bipartisan majority in Congress has voted to halt U.S. support for the Saudi-led war in Yemen but President Donald Trump vetoed the legislation. Democrats in Congress said the Trump administration expedited the arms packages because it could not secure a majority of lawmakers to support any proposed sales to the Saudis.
