Boehner says U.S. on path to default if Obama won't negotiate

WASHINGTON (Reuters) - Republican House Speaker John Boehner vowed on Sunday not to raise the U.S. debt ceiling without a "serious conversation" about what is driving the debt, while Democrats said it was irresponsible and reckless to raise the possibility of a U.S. default.

"The nation's credit is at risk because of the administration's refusal to sit down and have a conversation," Boehner told ABC's "This Week," adding that there were not enough votes in the House of Representatives to pass a "clean" debt limit bill, without any conditions attached.
