Senate Minority Leader Chuck Schumer, D-N.Y., warned Senate Republicans there will be "unintended consequences" if lawmakers pass their tax reform bill in the coming days, arguing the bill will "haunt" them in 2018 and future elections.

"There will be unintended consequences," Schumer said of the bill's potential passage. "The rush to get something, anything done will haunt my Republican colleagues in years to come, and — I dare say — in 2018."

Schumer slammed Republican leaders for going about their process in a partisan fashion since they only need 51 votes through the reconciliation process.

"We hear from the other side professing they want to work in a bipartisan way, but every step they take takes away bipartisanship," Schumer said, mentioning the reconciliation process and taking away the blue slips for judicial nominees as examples. "Unfortunately, the majority leader has taken steps this year to remove any hint of bipartisanship."

"This has been a very partisan bill," Schumer said. "That's why it's not a great product. That's why the other side is rushing it through. This is not a proud day for this chamber, and history will show that."

Senate Majority Leader Mitch McConnell, R-Ky., announced moments earlier Republicans would move forward with a "motion to proceed" vote Wednesday night, setting up a vote on a tax reform package for later in the week.

Republicans are still haggling over the final details of the package as they try to woo members to vote "yes" on it by the end of the week.
