WASHINGTON - When lawmakers return to Washington after Tuesday's congressional elections they will resume a debate they began with some reluctance last month on the US-led fight against Islamic State militants in Syria and Iraq.With the US-led coalition increasing air strikes but no signs the militants have been weakened, Congress appears ready for a broader discussion on the operations than it was prepared to hold during the run-up to the election.The temporary authorization for President Barack Obama's plan to arm and train moderate Syrian rebels - one element of the campaign - expires on Dec. 11, so lawmakers will have to take up that issue when they return from recess on Nov. 12.A handful of lawmakers are also pushing for Congress to consider a broader Authorization for the Use of Military Force (AUMF), which would set out guidelines for the overall effort to halt the militants.
