Senate leaders struck an unusual deal Wednesday afternoon to hold a vote on language that would block President Donald Trump from launching a war against Iran without congressional approval, paving the way for a final vote on the massive Pentagon policy measure on Thursday.
But the vote on the Iran amendment will happen on Friday, to accommodate Senate Democrats participating in presidential debates this week, a GOP aide said. If the chamber adopts the language, which has the support of at least two Republican senators, it would then be retroactively included in the fiscal 2020 defense authorization bill.
