The House is weighing whether to prohibit funds for the U.S. military operation against Libya in a constitutional showdown with President Barack Obama.
Lawmakers debated two amendments -- one to bar funds for military activities and equipment against Libya by Rep. Tom Cole, and a second by Reps. Dennis Kucinich and Justin Amash to prevent funds for military force against Libya.
Republicans and Democrats called the war illegal because Obama never sought congressional consent for U.S. participation in the NATO-led mission.
The House considered the measures as part of a $649 billion defense spending bill that wouldn't go into effect until Oct. 1. The House voted overwhelmingly last month against giving Obama the authority to continue the military mission but stopped short of cutting off funds.
