(CNN) Senate Majority Leader Mitch McConnell is pushing an amendment to a Middle East policy bill that would acknowledge "al Qaeda, ISIS and their affiliates in Syria and Afghanistan continue to pose a serious threat to us here at home," a move seen as a sharp rebuke to President Donald Trump's push to withdraw US troops from Syria.

"It would recognize the dangers of a precipitous withdrawal from either conflict and highlight the need for diplomatic engagement and political solutions to the underlying conflicts in Syria and Afghanistan," McConnell said Tuesday from the Senate floor, announcing the amendment to the bill, which is currently being debated.

Exact timing for the final vote on the bill, which at this point enjoys bipartisan support, has not yet been determined.

McConnell added that, "while it is tempting to retreat to the comfort and security of our own shores, there is still a great deal of work to be done.....we're not the world's policemen, but we are the leaders of the free world."

Trump ordered a rapid withdrawal of troops from Syria on December 19, a move that was widely criticized by lawmakers from both parties.
