Who is Senate parliamentarian? What to know about staffer Trump seeks to overrule
At the heart of the debate over the 'Big, Beautiful Bill' stands one little-known official: the Senate parliamentarian.
The low-profile congressional official has been thrust into the spotlight after issuing a procedural decision on the GOP-backed spending bill, drawing sharp responses from some Republicans.
President Donald Trump himself has even weighed in, calling for the 'unelected senate staffer' to be ignored.
Who is the Senate parliamentarian? What powers do they have? And why are Republicans up in arms? Here is what to know.
Who is the parliamentarian?
The Senate parliamentarian is a nonpartisan advisor who makes recommendations to lawmakers regarding the interpretation of rules and precedents in the upper chamber.
The role was established in 1935 amid the passage of a slew of New Deal-era laws, which 'expanded opportunities for procedural confusion and mischief,' according to Senate records.
The parliamentarian is appointed by the Senate majority leader and serves at their pleasure, according to the National Constitution Center.
The official's rulings are not necessarily final.
The presiding officer of the Senate — typically the vice president or the president pro tempore — can simply ignore their advice, according to the Bipartisan Policy Center.
This has happened a few times in recent history, including in 2017, when GOP lawmakers changed Senate rules to allow Supreme Court nominees to be confirmed with a simple majority.
That said, the Senate typically adheres to the parliamentarian's guidance, according to Time. This included in 2021, when the staffer rejected Democrats' attempt to include a pathway to citizenship for illegal immigrants in the 'Build Back Better' bill.
Currently, the office of the parliamentarian is held by Elizabeth MacDonough, who has served in the position since 2012. She was appointed by then-Senate Majority Leader Harry Reid, a Democrat.
MacDonough formerly worked at the Senate library and as a trial attorney, according to the Wall Street Journal. She also advised former Vice President Al Gore during a recount dispute following the 2000 election.
Why are Republicans upset?
Some Republicans expressed outrage at the parliamentarian after she issued rulings on the 'Big Beautiful Bill,' which is currently being considered by the Senate, following its passage in the House in May.
In late June, MacDonough ruled that a series of provisions in the bill violate the Senate's Byrd Rule, which prohibits 'extraneous' provisions from being included in budget reconciliation bills.
One such provision would have charged immigrants a $1,000 fee to apply for asylum in the U.S., according to The Hill.
MacDonough also ruled against several provisions that affect Medicaid. One was a proposed cap on provider taxes, which states use to fund Medicaid, according to CNBC. Another would block noncitizens from accessing Medicaid in addition to other health programs, according to USA Today.
In response to these proposed changes, multiple GOP lawmakers telegraphed their frustration with MacDonough.
'The WOKE Senate Parliamentarian, who was appointed by Harry Reid and advised Al Gore, just STRUCK DOWN a provision BANNING illegals from stealing Medicaid from American citizens,' Sen. Tommy Tuberville, a Republican from Alabama, wrote on X, formerly Twitter, on June 26. 'THE SENATE PARLIAMENTARIAN SHOULD BE FIRED ASAP.'
Rep. Greg Steube, a Florida Republican, also singled out MacDonough for criticism.
'How is it that an unelected swamp bureaucrat, who was appointed by Harry Reid over a decade ago, gets to decide what can and cannot go in President Trump's One Big Beautiful Bill?' he wrote on X.
He then called on Vice President JD Vance — using his power as the presiding officer in the Senate — to ignore the proposed changes.
Trump appeared to concur with this view.
'Great Congressman Greg Steube is 100% correct,' he wrote on Truth Social on June 29. 'An unelected Senate Staffer (Parliamentarian), should not be allowed to hurt the Republicans Bill. Wants many fantastic things out. NO!'
However, Senate Majority Leader John Thune, a South Dakota Republican, poured cold water on the push to sideline MacDonough.
When asked by Politico about overruling her on June 26, Thune said, 'No, that would not be a good option for getting a bill done.'
Meanwhile, other Republicans have defended MacDonough.
North Carolina Sen. Thom Thillis, who recently announced he will not seek reelection, called her a 'straight shooter,' according to Reuters. And Louisiana Sen. John Kennedy told reporters, 'Nah, never overrule the parliamentarian.'

Rep. Greg Steube says passing Trump megabill in the House will likely ‘be a challenge'
Rep. Greg Steube (R-Fla.) said on Monday passing President Trump's 'big, beautiful bill' in the House will likely 'be a challenge.' 'I do think you're gonna have some challenges on the House side. We can only lose three votes,' Steube told NewsNation's Blake Burman on 'The Hill.' 'You've got 218 you got to get to, we can only lose three, if we lose four the bill's dead, and you've got things in here that moderates don't like, and you've got things in here that conservatives don't like. So, it is certainly going to be a challenge.' House moderate Republicans and hard-line conservatives have recently expressed rising opposition to the Senate's version of the 'big, beautiful bill' only days before the lower chamber is set to consider the legislation. Democrats have already expressed their own vehement distaste for the bill, with members like Rep. Pramila Jayapal (D-Wash.) calling it a 'big bad betrayal bill' and Rep. Maxwell Frost (D-Fla.) saying it is an 'evil bill.' 'If Republicans pass this big bad betrayal bill, they are quite literally ensuring that more poor Americans will DIE so that billionaires and giant corporations can get a tax cut,' Jayapal said in a post on the social platform X Monday. Former close Trump ally Elon Musk said Monday he would support primary challengers to any Republicans who backed Trump's 'big, beautiful bill.' 'Every member of Congress who campaigned on reducing government spending and then immediately voted for the biggest debt increase in history should hang their head in shame!' Musk said on X.

Democrats fail to overturn ruling that tax cuts in GOP megabill don't add to deficit
The Senate voted along party lines Monday that making the expiring 2017 tax cuts permanent as part of President Trump's 'big, beautiful bill' could be scored as deficit neutral and therefore comply with the Byrd Rule, allowing the bill to pass with a simple-majority vote. Democrats failed to defeat the ruling by the Senate chair, which Republicans control, that the chamber's 940-page One Big, Beautiful Bill Act does not violate the 1974 Congressional Budget Act by using a controversial 'current policy' baseline to score the extension of President Trump's expiring tax cuts as not adding to the deficit. If the tax portion of the bill were scored on a 'current law' baseline, which assumes the 2017 Trump tax cuts would expire at the end of 2025, then it would add an estimated $3.5 trillion to federal deficits between 2025-34 and would add to deficits after 2034 — beyond the 10-year budget window allowed by the Byrd Rule. Scored this way, the Republican bill would fail the rule, which governs what legislation is eligible to pass the Senate with a simple-majority vote on the reconciliation fast track, and Republicans would be forced to rewrite large parts of the measure. But when scored with a 'current policy' baseline, the Congressional Budget Office projects the tax cuts in the Finance Committee's section of the bill would increase deficits by not more than $1.5 trillion between 2025-34 and would not increase on-budget deficits after 2034. Democrats argued a current policy baseline had never been used before in a budget reconciliation bill, and had never been used to score an extension of expiring tax cuts as not adding to future deficits, and therefore was not in compliance with the Senate's Byrd Rule. And Democrats highlighted over the weekend that most of the Republican reconciliation package uses a 'current law' baseline to project the cost of the legislation. Senate Democratic Leader Chuck Schumer (N.Y.) accused Republicans of 'deploying fake math and budgetary hocus-pocus to make it seem like their billionaire giveaways don't cost anything.' Senate Finance Committee ranking member Ron Wyden (D-Ore.) accused Republicans of 'going nuclear' to blow up the Senate rules so they can make Trump's 2017 tax cuts permanent. 'This is the nuclear option. It's just hidden behind a whole lot of Washington, D.C., lingo,' Wyden said on the floor. Wyden pointed out through a parliamentary inquiry that the Finance portion of the bill used two different baselines, current policy and current law. Senate Democrats had tried to schedule a meeting with Republican Budget Committee staff and with the parliamentarian to discuss whether using a current policy baseline violated Senate precedent and the Byrd Rule, but Republicans 'flat-out refused' to participate in such a meeting, according to a person familiar with the conversations. Senate Budget Committee Chair Lindsey Graham (R-S.C.) said Monday morning that Republicans are not overruling the parliamentarian and asserted the parliamentarian has said it is up to him as Budget chair to set the baseline. And he argued Democrats in the past have supported the use of a current policy baseline to project the cost of legislation, although it hasn't been done before for a budget reconciliation package. He noted former Democratic Budget Committee Chair Kent Conrad (N.D.) used a current policy baseline for a past farm bill. Republicans also point out former President Obama's budget office supported using a current policy baseline to score the extension of the expiring tax cuts from the George W. Bush era at the end of 2012. Senate Majority Leader John Thune (R-S.D.) said on the floor Monday that former Obama Director of the Office of Management and Budget Jeff Zients supported using the current policy baseline for the 2012 fiscal cliff deal.
