Senate Democrats on Friday ripped Republicans for making last-minute handwritten changes to a version of their tax-reform legislation mere hours before the chamber is expected to vote on it.

The version of the bill Democrats are criticizing does not include a final GOP amendment that hasn't been filed yet.

"Trying to review the #GOPTaxScam but they are making hand-written changes to brand new text as we speak – can anyone else read this?" tweeted Sen. Dick DurbinRichard (Dick) Joseph DurbinSenate approves resolution warning Trump not to hand over US officials Deal to fix family separations hits snag in the Senate Senate Democrats block resolution supporting ICE MORE (D-Ill.), sharing the same page of the law.

Durbin also criticized the process on the Senate floor, saying the GOP wrote out the bill "in longhand" and provided an illegible "work product" to lobbyists before handing it over to the senators voting on it.

The Senate is expected to vote on the sweeping legislation late Friday, following a day of negotiations among Republicans, almost all of whom need to vote for the bill for it to pass.

The legislation, if passed, would be the largest tax reform in the U.S. in three decades, marking a historic victory for the Republican Congress and the Trump administration.
