WASHINGTON (AP) -- The beheading of an American journalist in Syria appears unlikely to change U.S. lawmakers' minds about military intervention against Islamic State extremists.
President Barack Obama says the U.S. won't scale back its military posture in Iraq in response to James Foley's killing. But he's offering no specifics about what new steps he might take to protect additional captives and other Americans, and ward off what he describes as the al-Qaida offshoot's genocidal ambitions.
The initial response from members of Congress has been mixed, reflecting the divide of the American people. Hawks on Capitol Hill continue to assail the Obama administration's limited airstrikes in Iraq and its refusal to target Islamic State bases in neighboring Syria.
The president's supporters voice support for the current, cautious intervention in Iraq.
