US President Barack Obama Sunday spoke with House Minority Leader Nancy Pelosi about raising the government's borrowing authority  without other conditions attached, or a "clean" debt ceiling increase, the White House said Sunday.

 

 "The president and Pelosi discussed the way forward on the pressing fiscal matters facing Congress today. They reinforced that there must be a clean debt  limit increase that allows us to pay the bills we have incurred and avoid default," Xinhua quoted a White House statement as saying. 

 

 The first US government shutdown in 17 years drags on into its 13th day. US Treasury Secretary Jacob Lew has told Congress that the federal government will reach its debt ceiling of $16.7 trillion by Oct 17 and that failure to raise it would lead to a catastrophic default.

 

 "The House needs to pass the clean continuing resolution to open up the government and end the shutdown that is hurting middle class families and businesses across the country," said the readout of the discussion.

 

 US House Republicans have floated an idea of a six-week debt ceiling increase to avert a debt default crisis and urged fiscal reforms to cut government budget deficits. But Obama wants a longer-term debt limit increase without other conditions attached.

 

 "The president also thanked Pelosi for her efforts to move forward with a clean CR and a one-year clean debt limit increase that would prevent a first-ever  default of our nation's credit," noted the readout.

 

 However, Senate Republicans Saturday blocked a similar "clean" debt ceiling increase bill proposed by Senate Majority Leader Harry Reid, a Democrat, to extend the government's borrowing authority through the end of 2014 without other  conditions attached.
