Democratic senators are growing increasingly doubtful that Senate Majority Leader Charles Schumer (D-N.Y.) will be able to meet his Christmas deadline because several major disagreements are holding up the Build Back Better Act, including a fight over lifting the cap on state and local tax (SALT) deductions.

Schumer told reporters last week that his goal is to bring the $2 trillion bill to the floor the week of Dec. 13 but that timeline will be tough to meet because negotiators have a lot left to work out and Congress will also have to raise the debt ceiling by Dec. 15, which will distract attention from Biden’s agenda.

Sen. Kyrsten Sinema (D-Ariz.), a key player in the debate, is predicting to colleagues the legislation will likely wait until after the holiday season. Senate Democratic aides say passage of the bill in January is looking more realistic than before Christmas.

“I think there are issues with the parliamentarian’s office,” said one Democratic aide. “I don’t think there’s the person power in the parliamentarian’s office to get everything done quickly.”
