Democratic Sen. Claire McCaskillClaire Conner McCaskillDemocrats turn on Al Franken Trump rips Dems a day ahead of key White House meeting The Hill's 12:30 Report MORE (Mo.) said Friday that Democrats had received a list of amendments to the Republican tax reform legislation from outside lobbyists instead of their Republican colleagues. 

"This is so bad. We have just gotten list of amendments to be included in bill NOT from our R colleagues, but from lobbyists downtown," the senator tweeted ahead of a likely Friday vote on the bill.

McCaskill and other Senate Democrats have repeatedly criticized Republicans over their handling of the tax bill, arguing it is mostly being written behind closed doors.

The Senate is expected to hold a final vote on the legislation late Friday. A number of changes are likely to be made to the bill before final passage, however. Republicans are expected to offer a "manager's" amendment that would reflect those changes.

Senate Republican leaders said Friday that they had the votes to pass the landmark legislation.
