Senate Minority Leader Mitch McConnell (R-Ky.) on Sunday threw his support publicly behind a bipartisan proposal to raise the debt ceiling that had been gaining steam in the Senate on Friday before it was rejected by Democrats on Saturday.

The proposal, by Sen. Susan Collins (R-Maine), would raise the debt ceiling until Jan. 31 and fund the government through the end of March, while making only minor changes to the federal health care law.

Democrats want to extend the debt ceiling for a longer time period and to pass a shorter-term spending bill, one that would require broad budget talks before a new round of automatic budget cuts hit in January.
