The 'Gang of Six' Senators may hold the power to save the US from default.  

The U.S. Government borrowing authority ends on August 2. A failure by Democrats and Republicans to reach a deal on the debt ceiling could result in an event most economists for decades thought was unfathomable -- a default by the largest and most technologically advanced economy in the world.

On Aug. 4, the U.S. Treasury Department is due to pay off $30 billion in maturing short-term debt. In theory, the United States could prioritize debt payments, but U.S. Treasury Secretary warned lawmakers in Congress Wednesday that the prioritization tactic would still cause investors to shun U.S. Treasury securities, commonly known as Treasuries.

Republicans argue that Congress should substantially cut government spending to cut the budget deficit. Meanwhile, Democrats insist that revenue increases must be a part of the talks for any meaningful and enduring deficit reduction to occur.

But after struggling to reach an accord -- and apparently disbanding last week -- the Gang of Six says it's nearing an agreement on a proposal, which could offer an alternate strategy for pushing an increase in the debt limit through Congress before the Aug. 2 deadline.

So, who comprises this gang?
