Bullrich returned to the country after the 1982
Falklands War. Peronism lost the
1983 Argentine general election, so she joined the internal faction of
Antonio Cafiero that sought to renew the party. Peronism returned to power in 1989 when
Carlos Menem won the
1989 Argentine general election. She was elected deputy for the
Justicialist Party (PJ) in 1993, alongside
Erman González. Patricia Bullrich left the PJ in 1996 and started
New Leadership alongside
Gustavo Béliz. She had disagreements with him because she thought that he managed the party unilaterally, without making her part of the decisions. She left the party as a result and, after briefly considering joining the
Frepaso, she started another party. Initially named Cambio 97, it was soon renamed "Unión por Todos" (UPT) as the Cambio 97 name had already been registered. The new party did not get enough votes to allow her to be reelected as deputy in the
1997 Argentine legislative election. She then worked for the
Buenos Aires Province on security matters, assisting the municipality of
Hurlingham. She resigned in 1998, because of conflicts with
León Arslanián, minister of justice of the province. In 1999, the UPT became part of the
Alliance for Work, Justice and Education, which took
Fernando de la Rúa to the Presidency. Bullrich was appointed to office in the Department of Criminal Policy and Penitentiary Matters. In 2001, she was made a cabinet minister, as
Secretary of Labour, Employment and Human Resources and, later that year, as Secretary of Social Security. De la Rúa resigned, and eventually the governor of Buenos Aires
Eduardo Duhalde was appointed president by the Congress. Bullrich relaunched the UPT in 2002, aiming for the
2003 presidential elections. The party platform announced reforms on labor and education. The UPT did not take part in the elections, supporting instead
Ricardo López Murphy of the
Recreate for Growth party, who ended in the third place. Both parties united in the alliance "Unión para Recrear Buenos Aires", proposing Bullrich for mayor of Buenos Aires. She ended in the fourth place, with 9.76% of the vote. The UPT joined forces with the
Support for an Egalitarian Republic (ARI) and created the
Civic Coalition to run for the
2007 Argentine general election, with
Elisa Carrió as a candidate for president. Bullrich ran instead for deputy for Buenos Aires. Her centrist politics and polemical history as a government minister, however, contributed to the disenchantment of a group of left-wing members of ARI who left the Civic Coalition.
Minister of Security (2015–2019) '' organization.
Mauricio Macri was elected president in 2015 and Patricia Bullrich was appointed Minister of Security. Within the first days, three criminals convicted for
torturing and killing three pharmaceutical businessmen escaped from a high-security prison, leading to a nation-wide operation to recapture them. Bullrich announced on 9 January that the three criminals had been captured, but, in reality, only one had been captured. She tendered her resignation to Macri because of the mistake, but Macri rejected it. The other two criminals were captured a few days later. Bullrich proposed a protocol to remove roadblocks caused by
piqueteros. Such blocks should be announced in advance, restrict only part of the roads, and last for a short time. They should cease if ordered so by the police, and those who commit violent actions shall be detained. This protocol was approved by a meeting of the ministers of security of all provinces of Argentina.
Horacio Rodríguez Larreta, chief of government of the Buenos Aires city, and
María Eugenia Vidal, governor of the Buenos Aires province, refused to endorse it, as they thought that doing so could prove controversial. Instead, they preferred to negotiate and stay on good terms with organizations of piqueteros such as the
Evita Movement. Larreta also explained that the city does not need to endorse the protocols because it already has regulations for roadblocks.
Resistencia Ancestral Mapuche (RAM) and the
Coordinadora Arauco-Malleco (CAM), two
Mapuche organizations that normally operate in
Patagonia, expanded their attacks to the city of Buenos Aires. Their goal is to create a Mapuche nation, seceding from Argentina and Chile. Bullrich said that "We won't allow an autonomous mapuche republic inside Argentina; that's the logic of their request, the denial of the Argentine state, the anarchist logic. Our resolution is total and absolute in not allowing a group that uses violence as a way of action in Argentina." Facundo Jones Huala, leader of RAM, claimed to be a political prisoner, and that the RAM only acts in self-defense on lands that used to belong to them. Bullrich organized a joint command with the ministers of security of the
Neuquén,
Río Negro and
Chubut provinces against the RAM, and delivered a report of the actions taken against the organization, including 96 lawsuits, 2 of them for murder. The
Argentine National Gendarmerie forced a group of Mapuche demonstrators to cease a roadblock next to the
Chubut River, and the demonstrator
Santiago Maldonado went missing after that. The case became a national scandal, with the Gendarmerie (by extension their political authorities, Bullrich and Macri) being accused of an
enforced disappearance. Bullrich gave her full support to the Gendarmerie. Maldonado was found dead some months later, drowned in the Chubut river. Bullrich said "The whole world saw what happened with Maldonado. He stayed in the same place where he drowned, without being seen or touched by anyone. Neither the Gendarmerie nor our government would have made a person disappear". Bullrich and Macri supported the actions of Chocobar, on the grounds that it would be a
right of self-defense, Adrián Marcenac, father of Alfredo Marcenac, a student from
Necochea who was murdered by serial shooter
Martín Ríos in July 2006 in
Belgrano, Buenos Aires, labelled Bullrich's comments as "enormously grave" for Argentine society.
Presidential candidate posted by
Javier Milei to announce his alliance with Bullrich. Milei associates himself with imagery of lions, and "pato" ("duck") is a common nickname in Spanish for people named "Patricia". Bullrich, who was appointed president of the PRO in 2020, maintained a positive relationship with Milei, and at one point considered forming an alliance for the
2023 Argentine general election. However, Milei ultimately decided to run independently with his own party. There was an expectation that Mauricio Macri would run for president once again, as even in defeat he had gotten 41% of the vote in 2019 and his image had improved since then. However, he declined to do so, so the party had primary elections between Bullrich and Horacio Rodríguez Larreta. They represented the "hawks" and "doves" of the party. Macri did not openly side with any of them. Bullrich chose the former legislator
Luis Petri, from the UCR, as the candidate for vice-president. Petri had lost the primary elections for governor of Mendoza to
Alfredo Cornejo a short time before. She chose him because he was young, sided with the "hawks", and was not from Buenos Aires; and also because he worked with her during her time as minister of security. As Petri was from the UCR, Bullrich would secure the support of the radicals that were not pleased with the leadership of
Gerardo Morales (who supported Larreta), and with the whole party if Larreta was defeated in the primaries. Other politicians briefly considered to run for vice-president under her were
Carlos Melconian,
Maximiliano Abad,
Luis Naidenoff, and
Ricardo López Murphy. Carlos Melconian was proposed instead as Bullrich's potential minister of economy. In contrast with Milei, who proposed a full
dollarization of the economy, Melconian proposed instead a bimonetary economy, where both the
Argentine peso and the
United States dollar would be legal tender. Before implementing it, the fiscal deficit would be eliminated, the by-laws of the Central Bank would be amended to prohibit
money creation, and the restrictions on the use of US dollars would be removed. She also proposed the creation of a maximum security prison named after former president Cristina Kirchner. The primary elections ended with a decisive victory of Bullrich over Larreta. Once the primaries were concluded, the candidates took part in the
presidential debates, explaining their positions and proposals over several topics. Bullrich promised to end inflation, and to end the roadblocks caused by piqueteros. Although the primary elections ended with the three main candidates, Bullrich, Milei and Peronist
Sergio Massa in a close tie, Massa got ahead in the general election and won with 36% of the vote, followed by Milei with 30%. As a result, both candidates went to a third
ballotage election. Bullrich did not take part in it, as JXC ended in third place, but both candidates sought to get the support of her voters. Massa made a speech about institutional stability and public security, usual topics of the UCR and PRO respectively, and Milei focused on the need to join forces against Kirchnerism. On 25 October 2023, Bullrich officially endorsed Javier Milei for the runoff election. She did not ask the other parties within JXC, the UCR and the CC, for their opinion, as they have conflicting views over Milei. Both of them met the Wednesday after the elections to negotiate this support, alongside Macri. Milei announced the alliance on his
X account, with an
AI image of an embrace between a lion and a duck. Milei associates himself with imagery of lions, and "pato" ("duck") is a common nickname in Spanish for people named "Patricia".
Minister of Security (2023–2025) . In December 2023, Patricia Bullrich returned to government as security minister in president
Javier Milei's Cabinet. Bullrich immediately issued a protocol to deal with demonstrations and roadblocks made by
piqueteros. The
Workers' Party made an
habeas corpus request to prevent the protocol from coming into force, which judge Gustavo Pierretti rejected. Several groups of Piqueteros called for a massive demonstration on 20 December, a week after the
inauguration of Javier Milei. The government announced that demonstrators who committed crimes during demonstrations, such as roadblocks or vandalism, would lose their welfare payments, and provided a phone number to denounce piquetero leaders who would be coercing people to take part in such demonstrations. The demonstration had very little attendance, and the phone calls were used to start 660 criminal complaints. The policies were kept for all later protests. The welfare aid that was outsourced to piquetero organizations returned to the direct state control, and social leaders that worked at the
ministry of Social Development despite the conflict of interest were fired. Several audits also revealed that several social organizations that used to control the outsourced welfare aid only used a fraction of it for such a purpose. All this decreased the power of piqueteros, and protests and demonstrations rapidly decreased in size. The city of
Rosario had ongoing problems with narcotics trafficking cartels, who had moved beyond the
illegal drug trade into other illicit activities, such as
extortion and
contract killing. Bullrich announced the "Plan Bandera" ("Flag plan") with
governor of Santa Fe Province Maximiliano Pullaro to deal with the problem. One of the initial actions was to enforce stricter conditions at the local prisons, as several crime bosses were already jailed but managed to control the criminal operations nonetheless. The national government installed
mobile phone jammers at those prisons, which led to death threats against Pullaro and his family. Bullrich provided a report of the results of the operation six months later: homicides decreased by 73%, they detained 400 people linked to drug trade, 118 kilograms of cocaine and dope, 50,000 parts of
synthetic drugs, 900 kilograms of ammonia, 57,005,062
pesos, 18,050 US dollars and 70 weapons. Bullrich stayed president of PRO despite being a minister of a government for another party. Initially, both PRO and LLA were allies, but as both parties began to drift apart she sided with Milei's party instead of PRO. Both parties ran for the 2025 legislative elections on their own after the failure of the negotiations to create an electoral alliance. Bullrich took part in electoral parades of LLA, and encouraged politicians close to her move to the party. In May 2025 she formally left the PRO and joined LLA. Following her election as senator in the 2025 legislative election, on 22 November 2025 President Javier Milei confirmed that
Alejandra Monteoliva would be her successor. Bullrich resigned on 1 December 2025 and Monteoliva took office the following day. == Political positions ==
