[5] In 2024, investigations by the Supreme Federal Court revealed that general Freire Gomes was one of the army officials positioned against the 2022 Brazilian coup plot.

Witness testimony provided by Brazilian Air Force commander Carlos de Almeida Baptista Júnior says that, in the reunion where the coup meetings with then president Jair Bolsonaro took place, Freire Gomes threatened to arrest the president if he tried to proceed with the coup attempt.

In cellphone messages recovered by the Federal Police of Brazil between Walter Braga Netto and former captain Ailton Barros, if Gomes continued to resist the coup he should be "thrown to the lions" and "his head should be offered".
