Unknown Senate official wields more power to stop presidents than most lawmakers

Elizabeth MacDonough has served as Senate Parliamentarian since 2012 and is responsible for enforcing the Byrd Rule on budget reconciliation bills

The One Big Beautiful Bill Act (H.R. 1) passed the House by a 215–214 vote and runs over 1,100 pages (https://www.congress.gov/bill/119th-congress/house-bill/1)

Under the Byrd Rule, reconciliation provisions must relate directly to federal spending or revenue and cannot increase the deficit beyond a 10-year budget window

Senate reconciliation bills are limited to 20 hours of debate and can pass with a simple majority (51 votes), bypassing the usual 60-vote filibuster threshold

Eleven House committees were instructed to draft portions of the reconciliation bill, collectively producing more than $1.5 trillion in mandated savings
