Senate Minority Leader Chuck Schumer predicted that Republicans will "rue the day" they voted for the tax bill.
That day was delayed because of Senate rules, which prevent the bill from including any measures considered "extraneous" to budget matters. After the House passed what was believed to be the final version of the bill on Tuesday, Democratic senators challenged provisions relating to education and a technical issue over the naming of the bill. The Senate parliamentarian ruled that they did not fit inside the budget rules that the bill is being passed under, which allow it to be approved by a simple 51-vote majority, bypassing any risk of a Democratic filibuster.
