Senate Minority Leader Chuck Schumer, D-N.Y., declared Tuesday House Republicans will launch "open warfare" against middle-class Americans after they unveil their tax reform bill on Wednesday.

"When the House Republicans unveil their bill tomorrow, they'll essentially be initiating 'open warfare' on the middle class," Schumer said, pointing to their proposal to eliminate the state and local tax deduction in many high tax states, including New Jersey, New York, and Massachusetts.

Schumer argued Republicans should levy a higher tax on upper-class individuals and against wealthy corporations rather than against the middle class.

"They should have looked at the top 1 percent. They should have looked at the wealthiest corporations who are flush with money," Schumer said before mentioning the discussion surrounding potentially capping the 401(k) contribution limit.

House Republicans are set to release their plan on Wednesday ahead of an aggressive push to pass a bill by Thanksgiving. House Speaker Paul Ryan has also said he will keep the Congress in session around Christmas in order to pass a bill if it comes to that.

Schumer said he expects near-unanimous opposition in his own caucus against the GOP plan.

Back in August, 45 Senate Democrats signed a letter stating they will oppose any plan that does not tax the top 1 percent in any reform package. The three who did not sign the letter are Sens. Joe Manchin, D-W.V., Heidi Heitkamp, D-N.D., and Joe Donnelly, D-Ind.

"I don't know any of my Democratic colleagues who like the provisions in this bill. They'll make up their own minds, but 45 signed a letter, and three — when you hear what they have to say about the tax bill -- agreed with the principles in that letter."
