Quintero was controversially suspended from 10 May to 21 June 2022 by inspector general Margarita Cabello Blanco for allegedly attempting to interfere in the 2022 presidential election.

The youngest individual to hold that office thus far, Quintero was previously the Deputy Minister of the Digital Economy from 2016 to 2017, in the government of President Juan Manuel Santos.

Soon after he was born, the family moved to Tricentenario, a working-class suburb further north of the city center, where Quintero and his two brothers were raised by their single mother, Stella Calle, a self-employed woman.

To survive, Quintero and his brothers tried all sorts of informal self-employed jobs such as street vending, delivering parcels and selling home-cooked desserts.

The party did not achieve political representation because of it was unable to raise $230 million pesos to reach the required threshold applicable to local elections.

Upon Humberto de la Calle's defeat in the first round of the presidential elections, Quintero went on to support and campaign for the leader of the Colombia Humana Party, Gustavo Petro.

[7] Quintero posted a video on Twitter on 10 May 2022 and stated "change in the first", allegedly referencing a possible first-round victory of opposition Historic Pact presidential nominee Gustavo Petro.

Inspector general Margarita Cabello Blanco suspended Quintero as mayor several hours later for three months for allegedly attempting to interfere with the 2022 presidential election.

"[8] His suspension was denounced as unconstitutional by opposition politicians and members of the Medellín government, with legal experts asserting Cabello's actions may violate the law.
