Abraham Mendieta Rodríguez, Spanish political scientist and advisor to Morena, has caused controversy within the party. His influence in the Senate and the privileges he receives have caused discomfort among some legislators.
Although he is not Mexican and has not been elected, some members of Morena call him the "129th senator". The nickname refers to the 128 official senators of the Upper House.

Office in the Senate and benefits
Reports indicate that Mendieta has an office on the fifth floor of the Senate. This space was assigned to Senator Andrea Chávez, who now occupies another office as spokesperson for the caucus.
Additionally, he receives a considerable salary and has access to exclusive benefits for Morena legislators.
