WASHINGTON — Neither the House nor the Senate has a clear path forward for must-pass legislation to allow the government to continue to borrow to pay its bills, putting lawmakers and financial markets alike on edge less than a week before the deadline for heading off a first-ever U.S. default.

The pressure is on House Speaker John Boehner, who's being forced to rewrite his debt and budget plan after nonpartisan congressional scorekeepers said it wouldn't reap the savings he's promised.

The Ohio Republican also needs to shore up his standing with tea party-backed conservatives demanding deeper spending cuts to accompany an almost $1 trillion increase in the government's borrowing cap.

Unless he can regain control, Boehner risks losing leverage in his dealing with President Barack Obama and Democrats controlling the Senate.
