Pasco is a station on Line A of the Buenos Aires Underground. The station belonged to the inaugural section of the Buenos Aires Underground opened on 1 December 1913, which linked the stations Plaza Miserere and Plaza de Mayo. Like the Alberti station, it only has one platform, which in this case only serves passengers traveling to Plaza de Mayo. The other platform (the ghost station Pasco Sur) is located just a few meters away, but was closed in 1953 since the proximity of Alberti station meant having so many stops in such quick succession slowed the line's frequency.

The Palace of the Argentine National Congress (Spanish: Palacio del Congreso de la Nación Argentina, often referred locally as Palacio del Congreso) is a monumental building, seat of the Argentine National Congress, located in the city of Buenos Aires. It is located in the barrio of Balvanera at its limit with Monserrat, an area informally known as the Congreso neighbourhood. Constructed between 1898 and 1906, the palace is a National Historic Landmark. The Kilometre Zero for all Argentine National Highways is marked on a milestone at the Congressional Plaza, next to the building.

The Congress of the Argentine Nation (Spanish: Congreso de la Nación Argentina) is the legislative branch of the government of Argentina. Its composition is bicameral, constituted by a 72-seat Senate and a 257-seat Chamber of Deputies. The Senate, whose members are elected to six-year terms renewable by thirds each two years, consists of three representatives from each province and the federal capital. The Chamber of Deputies, whose members are elected to four-year terms, is apportioned according to population, and renews their members by a half each two years. The Congressional Palace is located in Buenos Aires, at the western end of Avenida de Mayo (at the other end of which is located the Casa Rosada). The Kilometre Zero for all Argentine National Highways is marked on a milestone at the Congressional Plaza, next to the building.

The Chamber of Deputies (Spanish: Cámara de Diputados de la Nación), officially the Honorable Chamber of Deputies of the Argentine Nation, is the lower house of the Argentine National Congress (Spanish: Congreso de la Nación). It is made up of 257 national deputies who are elected in multi-member constituencies corresponding with the territories of the 23 provinces of Argentina (plus the Federal Capital) by party list proportional representation. Elections to the Chamber are held every two years, so that half of its members are up in each election, making it a rare example of staggered elections used in a lower house. The Constitution of Argentina lays out certain attributions that are unique to the Chamber of Deputies. The Chamber holds exclusive rights to levy taxes; to draft troops; and to accuse the President, cabinet ministers, and members of the Supreme Court before the Senate. Additionally, the Chamber of Deputies receives for consideration bills presented by popular initiative. The Chamber of Deputies is presided over by the President of the Chamber (Spanish: Presidente de la Cámara), who is deputized by three Vice Presidents. All of them are elected by the chamber itself.

Plaza Primero de Mayo is a square of Buenos Aires, Argentina, located in the neighborhood of Balvanera.

The Confitería del Molino (Spanish: The Mill) is an historical Art Nouveau style confitería (coffeehouse) in Buenos Aires, Argentina, located in front of the Palace of the National Congress and the Congressional Plaza, on the intersection of Callao and Rivadavia avenues in the barrio of Balvanera. It first opened on 9 July 1916 and closed in 1997, the year when it was declared a National Historic Monument by the Argentine Congress. In recent years it has become dilapidated and derelict. In 2014, a law passed by Congress expropriated the coffeehouse and mandated its restoration; restoration efforts began in 2016 and are, as of 2020, still ongoing.

The Honorable Senate of the Nation of Argentina (Spanish: Honorable Senado de la Nación Argentina) is the upper house of the National Congress of Argentina.

The Radical Civic Union (Spanish: Unión Cívica Radical, UCR) is a centrist and social-liberal political party in Argentina. It has been ideologically heterogeneous, ranging from social liberalism to social democracy. The UCR is a member of the Socialist International.Founded in 1891 by radical liberals, it is the oldest political party active in Argentina after the Liberal Party of Corrientes. For many years, the party was either in opposition to Peronist governments or illegal during military rule. The UCR's main support comes from the middle class. The party has stood for free elections, secularism, supremacy of civilians over the military, and liberal democratic values. Especially during the 1970s and 1980s, it was perceived as a strong advocate for human rights.It had different conformations and fractures and through them it ruled the country seven times with the presidencies of Hipólito Yrigoyen (1916–1922) and (1928–1930), Marcelo Torcuato de Alvear (1922–1928), Arturo Frondizi (1958–1962), Arturo Illia (1963–1966), Raúl Alfonsín (1983–1989) and Fernando de la Rúa (1999–2001).Since 2015, it has been a member of Cambiemos with Republican Proposal and Civic Coalition ARI, and supported Mauricio Macri in the 2015 and 2019 elections.

The Justicialist Party (Spanish: Partido Justicialista, IPA: [paɾˈtiðo xustisjaˈlista]; abbr. PJ) is a major political party in Argentina, and the largest branch within Peronism.Current president Alberto Fernández belongs to the Justicialist Party (and has, since 2021, served as its chairman), as well as former presidents Juan Perón, Héctor Cámpora, Raúl Alberto Lastiri, Isabel Perón, Carlos Menem, Ramón Puerta, Adolfo Rodríguez Saá, Eduardo Camaño, Eduardo Duhalde, Néstor Kirchner, and Cristina Fernández de Kirchner. Justicialists have been the largest party in Congress almost consistently since 1987. Founded by Juan Perón, it was previously called the Peronist Party after its founder. It is overall the largest party in Congress; however, this does not reflect the divisions within the party over the role of Kirchnerism, the left-wing populist faction of the party, which is opposed by the dissident Peronists (also known as Federal Peronism or Menemism), the conservative faction of the party.
