Talks Underway To Possibly Rescind Portions Of Omnibus

Lawmakers would have to draft bills, send them through committee and pass them through both chambers within 45 days. While omnibus spending cuts would likely pass the House with conservative support, they would face an uphill battle in the Senate due to the unlikelihood of bipartisan support and the GOP's narrow majority.

But budgetary experts are unclear whether the infrequently used process would require a 60-vote procedural vote in the Senate, which would allow Democrats to block the bill from moving forward.

It's also unclear how much funding would be rolled back and which omnibus provisions would be targeted if they opt to move forward with the maneuver.

Rescission was once common practice. Government Accountability Office testimony in 1992 found that every president had offered some sort of rescission request to Congress from 1974 until that point, and that Congress had approved about a third of those requests. The testimony also found that rescission had little effect on overall deficits, due to their relatively small scale in the scheme of government spending.
