GOP leaders are set to hold off a vote on the sweeping tax bill until after the Congress returns from its summer recess.
The Senate Finance Committee voted Monday to advance the measure through its conference, but a delay on the measure could allow some senators to get on with the legislation and avoid a potentially embarrassing floor vote on Thursday.
The GOP tax bill will now go to the Senate floor for a vote Thursday morning, and senators are expected to vote to advance it before they head home to return to their home states and resume their work on the fiscal cliff.
That vote is likely to be closely watched by President Donald Trump, who has been critical of the tax legislation in the past and has threatened to veto the bill if it passes the Senate.
The White House has said it will veto the measure if it fails to get the 60 votes it needs to pass the Senate, a hurdle that would allow it to go to a full vote on Wednesday.
Trump’s approval rating has plunged since he took office in January, with a new poll released Monday by Quinnipiac University showing that his approval rating stands at 41 percent.
His disapproval rating is at 37 percent.
Trump, in a series of tweets Sunday, slammed Senate Majority Leader Mitch McConnell and his Republican colleagues for failing to pass a bill.
The president also said he would not be signing a bill to help the middle class and that he has asked Vice President Mike Pence to work on a tax plan to replace the bill.
Sen. Rand Paul, R-Ky., and other GOP senators have said they are going to use procedural means to force a vote that would force Trump to sign the bill into law.
But the Senate is controlled by a Republican majority and the measure faces an uphill battle in its current form, given the lack of support among Republicans.
Trump has called the tax plan a “massive gift” to the wealthy and has vowed to “crush” it if he is elected president in November.
