Their proposal has gained support within the Republican caucus, but Senate Democrats have not yet signaled they would include it in any package that raises the debt ceiling above the $14.3 trillion level set by Congress last year. The Obama administration has said the U.S. could hit the $14.3 trillion debt level as soon as March 31, and they are pushing Congress to raise the limit soon. As of Friday, federal debt subject to the limit stood at $14.008 trillion.

The Hatch/Cornyn plan would, among other things, mandate total budgetary outlays for any fiscal year not exceed revenues; cap federal spending at 20% of GDP; prohibit revenue raising moves that aren’t approved by two-thirds of the House and Senate.

The House and Senate would have to sign off on any exemptions, with a two-thirds vote. Provisions could also be waived if there is a formal declaration of war or because of national security concerns.

White House officials have said they don’t want to couple a debt ceiling vote with any spending restraints, but many Republicans have said they won’t vote to raise the debt ceiling unless there are major cuts in spending.
