Argentina’s political landscape was jolted this week when Congress, for the first time in over two decades, overturned a presidential veto—an act that not only challenges President Javier Milei’s authority but also sets the stage for a high-stakes electoral season. On Thursday, September 4, 2025, the opposition-controlled Senate voted decisively, 63 to 7, to overrule Milei’s veto of a bill that increases spending and protections for people with disabilities, according to reporting from Reuters and the Associated Press.
This landmark reversal marks the first time Congress has successfully overridden a full presidential veto since 2003, when President Eduardo Duhalde was in office. The lower house had already voted to overturn Milei’s veto in August, but it was the Senate’s overwhelming support that made the override official. The bill at the center of the storm boosts financial aid for people with disabilities and would increase government spending by 0.28% of Argentina’s gross domestic product this year and 0.46% next year, as estimated by the congressional budget office and cited by the AP.
President Milei, a self-described libertarian who swept into office in December 2023 on promises of radical reform, has dramatically shrunk government spending through a series of sweeping austerity measures. He argued that the disability benefits bill would threaten the country’s fragile fiscal balance, which he has worked to stabilize amid Argentina’s chronic inflation and repeated debt crises. Milei’s party, La Libertad Avanza, currently holds less than 15% of congressional seats and just seven out of 72 seats in the Senate, making legislative victories a steep uphill battle.
For much of his first year, Milei relied on extraordinary executive powers to push his agenda, but those powers recently expired, forcing him to negotiate with a Congress often hostile to his policies. As Semafor notes, building consensus has proven especially difficult for Milei, whose confrontational rhetoric has alienated many potential allies. The president has often used his veto power to block spending bills, hoping to maintain a much-vaunted fiscal surplus and reassure international investors wary of Argentina’s history of sovereign defaults.
But this time, even alliances with center-right lawmakers were not enough. The Senate’s vote, far surpassing the two-thirds majority required to override a veto, reflected broad opposition support for the disability benefits bill. During the heated session, senators did not shy away from linking the vote to recent scandals swirling around the Milei administration. Guadalupe Tagliaferri, a senator from the right-wing PRO party, pointedly declared, “When they ask me where the money to fund this law comes from, I’ll tell them it comes from overpricing and bribes.” Her remarks referenced allegations that have rocked the government in recent weeks.
At the end of August, local media published audio recordings allegedly implicating Diego Spagnuolo, then-chief of Argentina’s disability agency, in bribery schemes related to the awarding of medical contracts. The recordings also suggested that Milei’s influential sister and chief of staff, Karina Milei, was receiving kickbacks. The government responded swiftly, firing Spagnuolo, and President Milei publicly dismissed the allegations as a “lie.” Nonetheless, the scandal has added fuel to the opposition’s criticisms and cast a shadow over the administration’s handling of social welfare programs.
Centrist senator Alejandra Vigo underscored the human stakes of the new law, stating during the Senate debate, “For families, that percentage means the difference between sustaining the life of a person with disabilities or falling into despair.” The emotional arguments from both sides highlighted the deep divisions over how to balance fiscal prudence with social responsibility—a recurring theme in Argentine politics.
Meanwhile, the broader economic picture remains turbulent. The peso has continued to weaken, prompting the central bank to hike interest rates to levels that some say are suffocating commerce. Argentine stocks have plunged, and bond yields have soared, as markets brace for further instability ahead of a crucial round of elections. Polls now show Milei’s approval rating dipping below 40% for the first time since he took office, a sign that public patience with austerity may be wearing thin.
All eyes are now on the upcoming legislative elections in Buenos Aires province, scheduled for Sunday, September 7, 2025. While the outcome of this provincial contest may not directly alter national policy, Buenos Aires is a stronghold of the Peronist opposition and is often seen as a bellwether for the country’s political mood. The results could further rattle financial markets and raise fresh doubts about the viability of Milei’s radical reform program ahead of the more consequential national midterms in October.
The stakes for Milei couldn’t be higher. To fulfill his free-market agenda and restore investor confidence, he needs to expand his party’s presence in Congress. His minority status has left him vulnerable to legislative defeats, and the recent override of his veto is a stark reminder of the limits of executive power in Argentina’s democracy. Opposition parties, emboldened by their success, have already passed two other bills boosting state spending on health care and public universities in the past month, further challenging Milei’s efforts to rein in the budget.
Yet, the president’s supporters argue that his austerity measures are necessary medicine for an economy long plagued by overspending, inflation, and debt. They point to early signs that inflation has begun to cool—a tentative victory for Milei’s economic team. Critics, however, warn that the social costs of austerity are mounting, and scandals like the one engulfing the disability agency only deepen mistrust in the government’s ability to deliver fair and effective reforms.
As Argentina heads into a pivotal election season, the battle lines are clearly drawn. The veto override has energized opposition forces and exposed the vulnerabilities in Milei’s governing strategy. Whether the president can adapt, build new alliances, and regain public confidence will determine not just his political fate, but the direction of Argentina’s fragile recovery.
For now, as lawmakers and voters alike brace for a series of consequential decisions, the message from Congress is unmistakable: even in a system where executive power can loom large, checks and balances still matter, and the voices of the most vulnerable can, at least for one dramatic week, shape the national agenda.
