Senator Higinio Martínez Miranda will assume the presidency of the Senate's Steering Committee on September 1, succeeding Laura Itzel Castillo Juárez as head of the upper chamber, according to Expansión Política. The Morena caucus elected him this Sunday at its plenary meeting, and his appointment opens the new legislative session.

The transition comes on the eve of the new ordinary legislative session, with the 2027 midterm elections on the horizon, when 17 governorships, the entire Chamber of Deputies, and state legislatures are up for renewal, according to a letter that Senator Gerardo Fernández Noroña published and that Aristegui Noticias republished. Fernández Noroña, who presided over the Steering Committee during the first year of the current legislature before being succeeded by Laura Itzel Castillo Juárez, rejected the appointment and described it in that document as an agreement of "collusion with the opposition." Martínez, in response, said his presidency would be conciliatory but not weak.

In the letter, which circulated on his social media, Fernández Noroña argued that the vote was not unanimous but by majority, that he is not party to the agreement, and that Morena "is taking giant strides toward verticalism," a practice the movement fought against for decades. Martínez assured reporters at a press conference that they would seek votes from all senators, including that of Enrique Inzunza Cázares, a senator without party affiliation, to preserve Morena's qualified majority, and that his leadership would be grounded in the rules of procedure. "No, no, not soft. You cannot confuse the idea of conciliation and dialogue; that is doing politics," he said of the character of his presidency, adding that dialogue with the opposition is ongoing because consensus is necessary.

Martínez will formally take office on September 1, when the ordinary legislative session begins. The pace of debates and the majorities that take shape in the upper chamber will set the legislative calendar for September and, with it, the tone of dialogue among political forces.
