President Donald Trump reiterated on Tuesday that he wants US troops to be pulled out of Syria, but indicated that a decision had not yet been taken."I want to bring our troops back home. I want to start rebuilding our nation," Trump said, having indicated that US troops will leave once the Islamic State group is routed."Our primary mission in terms of that was getting rid of ISIS. We've almost completed that task," Trump said. "We'll be making a decision very quickly."Trump added that he would consult with allies and suggested that ally Saudi Arabia might pay the bill for US troops being there."Saudi Arabia is very interested in our decision. And I said, well, you know, you want us to stay maybe you'll have to pay."
