Elizabeth MacDonough is the Senate Parliamentarian, the nonpartisan official who advises the presiding officer of the U.S. Senate on how the chamber’s rules and precedents apply during legislative proceedings. Appointed in 2012 by Majority Leader Harry Reid, she was the first woman to hold the position since the office was created in 1935, and she still holds it in 2026. Her name surfaces in national news mainly during budget reconciliation fights, when her rulings determine which parts of a party’s signature bill can pass with 51 votes and which get stripped out.
What the Job Actually Is
The parliamentarian functions as the Senate’s institutional memory. When a senator raises a point of order or a parliamentary inquiry, the parliamentarian gives the presiding officer a recommendation grounded in the Standing Rules of the Senate and decades of accumulated precedent.1United States Senate. About Senate Rules2Congressional Research Service. The Office of the Parliamentarian in the House and Senate The presiding officer nearly always follows that recommendation, though nothing legally requires it.
Whenever the Senate is in session, MacDonough or a deputy sits at the rostrum just below the presiding officer’s desk, ready to answer procedural questions in real time. Off the floor, the office is available to any senator or staffer trying to work out what procedural tools are available for a particular bill, amendment, or motion.
The parliamentarian is appointed by the Senate Majority Leader and serves at the leader’s discretion. The expectation, though, is strict nonpartisanship. MacDonough has advised the chamber under both Democratic and Republican majorities, and that continuity is the point of the office: senators on both sides need a referee they can trust to call it straight.
Her Background
MacDonough earned a bachelor’s degree in English literature from George Washington University in 1988 and a law degree from Vermont Law School in 1998. Out of law school, she was selected through the Attorney General’s Honor Graduate program to work as an assistant district counsel for the Immigration and Naturalization Service, litigating federal immigration cases in New Jersey.3Vermont Law and Graduate School.

She later left the executive branch and joined the Office of the Senate Parliamentarian as an assistant, spending years under her predecessors absorbing the maze of Senate precedents that no rulebook fully captures. That long apprenticeship built the technical expertise and neutral reputation that made her a plausible successor when Alan Frumin retired in January 2012. Her appointment did not require Senate confirmation; the Majority Leader simply chose her.
Why Her Rulings Can Decide Major Legislation
The parliamentarian’s most consequential job involves budget reconciliation, an expedited procedure created by the Congressional Budget Act of 1974. Reconciliation lets Congress pass certain spending and tax legislation with a simple majority instead of the 60 votes usually needed to overcome a filibuster.4Congressional Research Service. The Reconciliation Process – Frequently Asked Questions Because reconciliation sidesteps the filibuster, both parties try to load these bills with as much of their agenda as they can. The Byrd Rule, codified at 2 U.S.C. ยง 644 and named for Senator Robert Byrd, exists to police that impulse.5Office of the Law Revision Counsel. United States Code Title 2 – Section 644
The rule sets out several tests for whether a provision belongs in a reconciliation bill. The one that kills the most high-profile provisions is the “merely incidental” test: if a proposal is really about changing policy and the fiscal impact is just a side effect, it fails. Any senator can raise a point of order against a provision they believe violates the rule. If the presiding officer sustains the objection based on MacDonough’s advice, that provision is struck. Overcoming a sustained Byrd Rule objection requires 60 votes, which defeats the purpose of using reconciliation in the first place.6Congressional Research Service.

So when MacDonough decides that a policy change primarily drives spending or that its budgetary effect is merely incidental, she is effectively deciding whether that policy can become law on a party-line vote.
The Rulings That Made Her a Household Name
The $15 Minimum Wage
In February 2021, MacDonough ruled that a provision gradually raising the federal minimum wage to $15 per hour could not be included in the American Rescue Plan, the COVID-19 relief package Democrats were advancing through reconciliation. She concluded that the wage increase was fundamentally a policy change whose budgetary effects were incidental to its regulatory purpose. The ruling killed one of the most prominent planks of the relief package.
Immigration Pathways
Later in 2021, Democrats tried three separate strategies to include immigration reform in the Build Back Better reconciliation bill. The first offered a pathway to citizenship for roughly eight million immigrants. MacDonough rejected it. The second used a registry date update to grant legal residency. She rejected that too. The third, more modest, sought work permits for long-term undocumented residents and faster processing of existing visa backlogs. She struck it down in December 2021, finding that all three versions had policy impacts that outweighed their budgetary effects.
The 2025 Republican Reconciliation Bill
MacDonough’s role drew renewed attention during the 2025 reconciliation effort. She struck language that would have expanded the use of expedited removal in immigration enforcement, finding that the procedural change exceeded what reconciliation allows. She ruled that the bill could rescind funding from Inflation Reduction Act clean energy programs but could not repeal the underlying authorization for those programs, meaning Congress could restore funding later. Provisions limiting student loan repayment options were allowed for future borrowers but could not be applied retroactively to current ones. A proposed exemption from an endowment tax for religious colleges was struck as extraneous. Several other provisions survived only after being rewritten.
The pattern across her rulings is consistent. Provisions framed around who gets money or how much can usually stay. Provisions that change legal status, create new regulatory frameworks, or restructure government authority tend to get flagged as policy changes with merely incidental budgetary effects.
How Secure She Is in the Job
The parliamentarian’s power is formally advisory. The presiding officer is the one who actually sustains or overrules a point of order, and the full Senate can vote to override that decision. In practice, presiding officers have almost always followed the parliamentarian’s advice, and no modern Senate has voted to disregard a Byrd Rule recommendation. The option exists; it just has not been used.
The majority leader can also replace the parliamentarian at any time without explanation. In 2001, Majority Leader Trent Lott pushed out Parliamentarian Robert Dove after Dove issued rulings that complicated Republican efforts to advance President Bush’s budget and tax proposals. That episode remains the clearest modern reminder that the office serves at the majority’s pleasure.
When MacDonough’s rulings on the minimum wage and immigration frustrated Democrats in 2021, some members openly called for firing her or having the Vice President overrule her from the chair. Leadership declined both options, judging that preserving the office’s credibility was worth more than winning any single fight. Her ability to survive leadership changes on both sides, and internal pressure to remove her, speaks to the trust her work has earned across the aisle. The authority of her position, though, still rests almost entirely on the norm that both parties choose to respect it.
