“The lengths to which Republicans are now going to in order to protect the rich from paying higher rates would be comical if they weren’t so detrimental,” Murray said on the floor Wednesday. “They say they’ve accepted that revenue needs to be on the table — but then the proposal Speaker BoehnerJohn Andrew BoehnerRestoring fiscal sanity requires bipartisan courage GOP congressman slams primary rival for Ryan donations Speculation swirls about Kevin McCarthy’s future MORE made to the president would actually cut rates for the rich.”

Democrats has proposed letting the Bush-era tax rates expire on incomes more than $250,000, while Republicans say raising taxes rates on anyone would harm the economy.

“House Republicans continue to hold the middle class hostage in a desperate and deeply misguided attempt to buck the will of the people, ignore the results of this election and protect the wealthiest Americans from paying higher taxes,” Murray said. “That’s really all there is to it.”

Murray said if the House approved the Senate-passed Middle Class Tax Cut Act, the GOP would get 98 percent of the tax cuts they’re asking for.

“Republicans don’t have to support taxes going up on the rich in order to vote for our bill to keep taxes low on the middle class,” Murray said. “Republicans can believe that the Bush tax cuts for the rich should be extended. They can remain committed to fighting for that misguided policy. And they can still vote on the portion of the tax cuts we all agree should be extended — those for the middle class.”

Lawmakers are working on a deficit-reduction plan to avoid the "fiscal cliff," which is set to take place at the beginning of next year when Bush-era tax rates expire and sequestration takes effect.
