The United Nations' readiness to lift the international arms embargo on Libya landed with a thud in Congress, where lawmakers were either blindsided by the announcement or downright skeptical.

A grand coalition including the United States, European Union, African Union, League of Arab States and several of Libya's neighbors came together May 16 in Vienna to endorse the coalition Government of National Accord in Tripoli and urge the UN to relax the embargo that has been in place since the 2011 uprising. Many lawmakers, however, remain concerned that blanket support for the fledgling government could lead to weapons ending up in the wrong hands and perhaps trigger greater US involvement in that country's messy conflict.

"This is an incredibly fragile government. I hope that we ask some very tough questions before we start arming a government that's on ice that's still pretty thin," said Sen. Chris Murphy, D-Conn. "Congress has abdicated its responsibility to oversee weapons sales. I think it's about time that we get back into the game and oversee what has been a fairly significant ramp up of weapons sales to the region." 

Murphy has taken the lead in questioning US bomb sales to Saudi Arabia for its campaign against the Houthis in Yemen.
