WASHINGTON (AP) — In the fight against Islamic State militants, members of Congress talk tough against extremism. But many lawmakers want to run for cover when it comes to voting on new war powers — preferring to let the president own the battle.

The U.S. military intervention in Iraq and Syria creeps forward, putting more pressure on Congress to vote on a new authorization for the use of military force.

Obama has been relying on congressional authorizations given to President George W. Bush for the war against al-Qaida and the invasion of Iraq.

Thirty-five Republicans and Democrats have called on new House Speaker Paul Ryan to schedule and debate on a war authorization.

Administration officials are to brief members of the Senate Foreign Relations Committee on the issue this coming week.
