[1] On April 20, 2022, Esquivel blocked the delivery of the investigation report of alleged acts of illicit financing by Pío López Obrador, brother of the president of Mexico, to the National Electoral Institute.

[11] The report was requested by the institute to the Attorney General of Mexico following a ruling by the Electoral Tribunal of the Judiciary of the Federation to determine the situation of Pío, who the previous year gained notoriety due to the leaking of a 2015 video in which David León Romero [es], a coordinator from the Ecologist Green Party of Mexico, gave him cash without a specific origin for "the movement".

[17] Authorities of the Facultad de Estudios Superiores Aragón[a] announced that they would investigate the report in detail and that if the plagiarism was confirmed, they would act in accordance with institutional regulations.

[19] President López Obrador expressed that "any error, any anomaly, committed by Minister Yasmín when she was a student, when she presented her undergraduate thesis, is infinitely less than the damage caused to Mexico by [Enrique] Krauze and the man making the accusation, Sheridan", and that the investigation was carried out to attack his government.

[20] Esquivel later shared letters of support and defense of her career from various lawyers and professors, including one from Martha Rodríguez Ortiz, her thesis advisor.

[23][24] On Christmas Day, Esquivel announced a complaint for plagiarism with the Mexico City's prosecutor's office, led by Ernestina Godoy Ramos, affirming that she began writing her thesis in 1985 and that she would continue with the process to become president of the SCJN on January 2, 2023.

[28] Hours later, the prosecutor's office issued a statement saying that although they received Esquivel's complaint, they determined that they could not proceed with the investigation since the statute of limitations had expired.

[27] On January 11, UNAM determined that Esquivel "substantially" copied Báez's thesis but that they did not have the authority to remove her bachelor's degree, which remained pending the Secretariat of Education's decision.
