The influential conservative Tea Party organization FreedomWorks is pushing back on a plan by Senate Minority Leader Mitch McConnell to hand much of the responsibility for raising the debt ceiling to President Obama.

"Sen. McConnell thinks cutting spending is too hard. Help him find his spine! Call him at 202-224-2541," the group tweeted.

The tweet came shortly after McConnell unveiled a plan urging Congress to pass legislation that would allow Obama to make a number of small increases to the debt ceiling.

In McConnell's plan, Congress could only stop Obama from raising the debt ceiling in comparably small increments by passing disapproval resolutions. The resolutions would require two-thirds' support in both the House and Senate to overcome Obama's veto.
