(CNN) Senate Majority Leader Mitch McConnell announced Friday the Senate will vote as early as next week on a broad Middle East policy bill, one that will allow senators to express their misgivings about President Donald Trump's controversial decision to bring US troops home from Syria.

The bill doesn't specifically counter the withdrawal -- a surprise move that alarmed foreign policy hawks like Republican Sen. Lindsey Graham of South Carolina but also more mainstream rank-and-file members from each party --- but does include new sanctions against the Syrian government that will open the door to debate about the sudden change in US policy and its impact.

Critics of the decision believe it will leave a void in war-torn Syria that could be filled by Russia and Iran.

Speaking on the floor, McConnell said he expects the Senate debate could be "contentious" and that he hopes the White House and Congress will be "deliberate and sober" as they consider US options in Syria.

"There are differing views about the role of the US military with respect to the threats emanating from Syria," McConnell said. "There is no question that we continue to face serious challenges from Al Qaeda and ISIS in Syria, as well as from Iran, Russia, and the Assad regime itself. And I anticipate this body will debate US military strategy towards Syria in coming weeks as it conducts oversight over the administration's apparently ongoing review of its policies."
