RNA - The Senate voted 71 to 27 to kill legislation that would have stopped the sale, Reuters reported.
The overwhelming vote stopped an effort led by Republican Senator Rand Paul and Democratic Senator Chris Murphy to block the deal over concerns including Saudi Arabia's 18-month-long aggression against Yemen and worries that it might fuel an ongoing regional arms race.
The Pentagon announced on Aug. 9 that the State Department had approved the potential sale of more than 130 Abrams battle tanks, 20 armored recovery vehicles and other equipment to Saudi Arabia.
The Defense Security Cooperation Agency said General Dynamics Corp would be the principal contractor for the sale.
Paul, Murphy and other opponents of the arms deal were sharply critical of the Riyadh government during debate before the vote, citing Yemen, the kingdom's human rights record and its international support for Wahhabism.
"If you're serious about stopping the flow of extremist recruiting across this globe, then you have to be serious that the ... brand of Islam that is spread by Saudi Arabia all over the world, is part of the problem," Murphy said.
The criticism came days before lawmakers are expected to back another measure seen as anti-Saudi, a bill that would allow lawsuits against the country's government by relatives of victims of the Sept. 11 terrorist attacks.
US President Barack Obama has promised to veto that bill, but congressional leaders say there is a strong chance that lawmakers will override the veto and let the measure become law. Overriding a presidential veto requires a two-thirds vote in both the House and Senate.
Saudi Arabia has been pounding Yemen since March 2015, with the UN putting the death toll from the military aggression at about 10,000.
But backers of the deal said Saudi Arabia is an important US ally in a war-torn region, deserving of US support.
"This motion comes at a singularly unfortunate time and would serve to convince Saudi Arabia and all other observers that the United States does not live up to its commitments," Senate Majority Leader Mitch McConnell said.
