Sanders, in an email to supporters, said “this week I will go to the floor of the United States Senate” to force a vote on his resolution.

“Despite Trump's venal support for the Saudi regime, I am confident that we now stand an excellent chance to win this vote which I plan on bringing back to the Senate floor this week,” Sanders added in the email.

A spokesman confirmed that Sanders will vote this week and is in talks with leadership to lock down a Wednesday or Thursday vote.

The vote on the resolution comes as Congress is searching for ways to respond to the killing of Washington Post contributor Jamal Khashoggi.

The vote will also offer lawmakers their first chance to test a formal rebuke of the administration, after the president said last week that the slaying wouldn’t impact the U.S.-Saudi relationship.

The briefing could give the administration a last-ditch chance to quell growing frustration with Saudi Arabia and undercut Sanders's resolution.

The Senate narrowly rejected a similar resolution in March, in a win for the administration which lobbied hard against the resolution at the time.

The resolution would require Trump to withdraw any troops in "or affecting" Yemen within 30 days unless they are fighting al Qaeda.
