Fox has learned that Reps. Peter DeFazio (D-OR), Jim McDermott (D-WA) and Jay Inslee (D-WA) are crafting a letter to share with the House Democratic Caucus that would try to prevent the Speaker from bringing the tax bill to the floor.

They hope to get 60 signatures on their letter (which is still being drafted) and then force a vote in the caucus. DeFazio says he thinks that if a majority of House Democrats are against this compromise, they shouldn't bring it to the floor.

In other words, they are seeking a majority of the majority to move this and a senior House democratic source indicates they don't know if they have a majority of democrats, saying they haven't whipped this yet.

In an interview with Fox, DeFazio criticizes the president and says a majority of the House Democratic Caucus does not support the tax rate compromise. "There does not seem to be a majority of the Democrats who support the deal negotiated by Vice President Biden," DeFazio said. "So we want to have a record vote in the caucus on a resolution that says this resolution should not go to the floor without a majority of Democratic votes."
