The Senate will vote on whether or not to discharge Paul's resolutions of disapproval, one on the sale to Bahrain and a separate on the Qatar arms sales, out of the Foreign Relations Committee. If he's successful it would kick the issue to the full Senate, and allow him to fast-track the two resolutions on the Senate floor.

"This proposed sale will support the foreign policy and national security objectives of the United States by helping to improve the security of a major non-NATO ally which is an important security partner in the region. Our mutual defense interests anchor our relationship and the Royal Bahraini Air Force (RBAF) plays a significant role in Bahrain's defense," the administration argued in its explanation for the arms sale.

The arms sale to Qatar that Paul is trying to block would provide apache attack helicopters and related equipment for $3 billion.

Paul could face an uphill bid to block the arms sale. The Senate previously rejected his attempt to block an arms sale to Bahrain late last year.

Paul argued at the time that it was about the Yemen civil war. Lawmakers have grown increasingly frustrated about the Saudi-led military campaign in Yemen, as part of growing angst on Capitol Hill about the U.S.-Saudi relationship.

Bahrain is a member of the Saudi Arabia-led coalition on which the bulk of the death toll is blamed.
