Political career
Early in his career, Martínez was active in a Christian youth organisation.[2] In 2005, he became a legislative aide at the National Chamber of Deputies for Santa Fe deputy Agustín Rossi, of the Front for Victory. Martínez would form a longstanding association with Rossi, serving in his office until Rossi's hiatus from Congress in 2013.[3] From 2015 to 2017, Martínez worked as an aide for Mendoza deputy Guillermo Carmona. He would later return to Rossi's office when the latter was once again elected to the lower house in 2017.[1]
In the 2019 legislative election, Martínez ran for one of Santa Fe's seats in the Chamber of Deputies in his own right, as the fourth candidate in the Frente de Todos list.[4] The Frente de Todos came second in the general election, with 42.26% of the vote, enough for Martínez to make it past the D'Hondt cut and be elected.[5]
As a national deputy, Martínez formed part of the parliamentary commissions on Industry, National Defense, Freedom of Expression, Petitions and Powers, Budgets and Finances, Addiction Prevention, Education, and Tax Norm Auditing. He also served as first vice president of the National Defense Commission.[1] He was a supporter of the legalisation of abortion in Argentina, voting in favour of the 2020 Voluntary Interruption of Pregnancy Bill.[6]
