Senate Majority Leader Harry ReidHarry ReidSanders and Schumer are right: Ellison for DNC chair The Hill's 12:30 Report Hopes rise for law to expand access to experimental drugs MORE (D-Nev.) harshly criticized Newt Gingrich (R-Ga.) on Monday for shifting his rhetoric on the House-passed Republican budget, which Democrats contend would "kill Medicare."

"Though the Republican House passed the Medicare-killing plan almost unanimously, sometimes it’s difficult to tell where the Republican Party stands generally," said Reid.

"Look how quickly one prominent Republican candidate spun himself in circles last week," said Reid. "First he called the plan for what it was — radical. He said it was right-wing social engineering, that's a quote. Hours later, after Republicans jumped all over him, he reversed course and said he supports the plan to kill Medicare."

"And remember he said it’s radical, it’s right-wing social engineering and suddenly he said it’s OK," concluded Reid. "That is some real interesting gymnastics."

Gingrich said last week he had apologized to Rep.

Gingrich's spokesman said his boss's previous comments had included "inartful terms."

The GOP plan would cut $5.8 trillion in spending over 10 years and transform Medicare into a sort of voucher system. It would balance the budget by 2040 without raising taxes. 
The budget proposal passed the House in March in a 235-193 with no Democratic support. Four Republicans opposed it.
