Senate 'Byrd bath' further complicates conservative support for tax bill

Republicans are staring down more complications this week with their One Big Beautiful Bill Act, this time from the Senate’s parliamentarian, who ruled against several provisions that they included to win over conservative support.

The House narrowly passed the tax and spending legislation last month after weeks of fierce negotiations. Now the bill is in the Senate, where parliamentarian Elizabeth MacDonough has ruled that specific provisions cannot pass using the special legislative process that allows Republicans to skirt the filibuster.
