Graham wants open-ended war authorization against the Islamic State

Saying the Paris attacks had changed the landscape, Sen. Lindsey Graham on Thursday offered the latest proposal to do what Congress has been reluctant to do: Formally authorize a military campaign against the Islamic State.

Graham's open-ended proposal comes closer than any previous one to an outright declaration of war against the extremist group, which controls parts of Iraq and Syria, is expanding to Libya and has taken credit for the Nov. 13 attacks in the French capital that killed at least 130 people. It would place no limits on time, geography or means used against the group.

"It is my firm belief that the United States should be at war with [the Islamic State] on the same terms that they are at war with us," said the South Carolina Republican, who's also seeking his party's presidential nomination.

"I look forward to this debate. If you don't agree with what I'm doing, fine. Just vote on it."
