Conservatives, including members of the Senate Tea Party Caucus, are also unhappy with the proposal.

McConnell's plan would require Obama to make three separate requests to raise the debt limit. Congress could pass resolutions of disapproval to block the requests, but those actions would require two-thirds' support in both chambers in order to override expected presidential vetoes.

The proposal from the Senate Republican leader would require Obama to request three tranches ranging between $700 billion and $900 billion. Those requests would be made at the end of this month, later this fall and in the summer of 2012.

It also would require Obama to recommend a greater amount of spending cuts for every dollar he requests to raise the debt limit.
