“We are in danger of fighting an expanded war… a war that was originally justified as a limited military operation.”

Udall said he opposes such an escalation, and that Congress must weigh in on whether President Obama has the authority to pursue the war.

“If the United States military is to be involved in such an escalation, then the United States Congress must exercise its constitutional authority and approve or disapprove of the president’s proposal,” Udall said.

Udall also accused some of his colleagues of “clamoring” to escalate the war in Libya.

“It is the responsibility of Congress to step forward, speaking for American people, to make a decision on whether or not we will go forward with a military commitment,” said Durbin. “We have an awesome responsibility under the Constitution.”

Members of Congress in both chambers and parties have been irritated with the administration over its lack of consultation with Congress over the action in Libya.
