Garré was born in the San Telmo district of Buenos Aires, and earned a law degree from the Universidad del Salvador when she was 22 years old. Her father, Raúl Garré, was a Peronist member of the Buenos Aires ProvinceHouse of Representatives until the 1955 coup against President Juan Perón in 1955. Elected in the March 1973 Peronist landslide, Garré became the youngest woman elected to Congress in Argentina to that date, and was among those on the flight that returned Perón to Argentina. She married Juan Manuel Abal Medina, who then was the Secretary-General of the Justicialist Party, in 1973. Following Perón's break with his party's left wing, Garré was among a group eight left-wing Peronists expelled from the Justicialist Party caucus in the Lower House in January 1974. She remained in Congress until its dissolution by the military dictatorship installed during the March 1976 coup. Informed, as were most lawmakers, that leftist elected officials would be targeted for imprisonment or assassination, she sought refuge with her husband at the Mexican Embassy, where Abal Medina remained for the next six years. She later joined the , a legal aid foundation established in 1979 to defend the human rights of those targeted by the dictatorship and request habeas corpus for these political prisoners. Obtaining safe conduct in 1982, Abal Medina sought exile in Mexico City and, after this separation, the couple were finally divorced. Garré became an ally of Catamarca Province Senator Vicente Saadi and of Peronist Renewal leader Antonio Cafiero upon the return of democracy in elections in 1983. She was given a post in a National Automobile Registry office, but reentered politics after President Carlos Menem's turn to the right during the early 1990s. She joined Chacho Álvarez's leftist Frente Grande in 1993, and was returned to the Chamber of Deputies in 1995 on the FrePaSo list formed by the Broad Front and other progressive parties. She was named Deputy Interior Minister by Minister Federico Storani in October 2000. The government of President Fernando de la Rúa of the Radical Civic Union, which was backed by FrePaSo in an Alliance, was in crisis, however, and Garré resigned in protest over the appointment of conservative economist Ricardo López Murphy as Minister of Economy of Argentina in March 2001. She returned to the Chamber of Deputies in 2001, serving until 2005. Garré served briefly as Ambassador to Venezuela in 2005, and helped organize demonstrations led by Venezuelan President Hugo Chávez at the 4th Summit of the Americas against U.S. President George W. Bush and the proposed Free Trade Area of the Americas. at the Pentagon Garré was recalled to join the government of President Néstor Kirchner as Defense Minister in November, becoming the first woman to hold that post in Argentina. She implemented numerous significant changes during her tenure, including policies promoting jointness within the Argentine Armed Forces and those emphasizing civilian leadership in national defense matters; until then each one of the armed forces had had a virtual autonomy on budget, procurement, organization and deployment. Garré was named to head the powerful new Security Ministry, established in December 2010 by President Cristina Fernández de Kirchner. The distribution of the Clarín and La Nación newspapers was blocked on March 27, 2011, and, according to one of these newspapers, the police did not act to prevent or stop this; the Argentine Federal Police operates under the aegis of the new Security Ministry. This was not the first time this had happened, and the government had already been enjoined by the judiciary to prevent further blockades. The Radical Civic Union proposed Garré's impeachment following this incident, albeit unsuccessfully. Garré has also reaped criticism by officials in Buenos Aires Mayor Mauricio Macri's administration for her decision to withdraw Federal Police officers from the city's hospitals, schools, subway stations, and other public places. Her successor at the Defense Ministry, Arturo Puricelli, was nominated by the president on May 30, 2013 to succeed her as Security Minister; she in turn was nominated as Argentine Representative to the Organization of American States. She resigned in 2015, when she was elected deputy for the Argentine Congress. Garré is one of numerous South American women who, around 2005, assumed leadership positions traditionally held by men. This group includes Chilean PresidentMichelle Bachelet and Garré's compatriot, Felisa Miceli, who served as Minister of Economy. This would later include Brazilian President Dilma Rousseff and Argentine President Fernández de Kirchner.
