Mexican President Claudia Sheinbaum convened an emergency session of her national security cabinet on Friday as the political fallout from a sweeping US indictment targeting cartel-linked officials continued to fracture her ruling Morena party. The closed-door meeting in Mexico City brought together the foreign minister, attorney general, and senior intelligence chiefs to coordinate a unified government response to Washington's move, which named several figures with alleged ties to party networks.

The crisis deepened overnight when at least three prominent Morena senators publicly contradicted the presidential palace's measured tone, calling instead for a formal diplomatic protest and the suspension of cooperation mechanisms with the US Drug Enforcement Administration. The open dissent represents one of the most visible internal splits Sheinbaum has faced since taking office, and analysts in Mexico City say it reflects deeper anxieties within the party about the Biden-era cartel strategy now being aggressively continued under the Trump administration.

Washington has so far declined to provide Mexico City with the full evidentiary files underpinning the indictments, a withholding that Sheinbaum's foreign ministry described this week as 'incompatible with sovereign cooperation.' Friday's session was expected to produce a formal diplomatic note to the US Embassy demanding procedural transparency, stopping short of the expulsion threats floated by opposition figures.

US Ambassador to Mexico Ken Salazar — whose tenure has been marked by repeated friction over cartel policy — was summoned to the Foreign Ministry building on Tlatelolco Plaza for consultations, according to two Mexican government officials briefed on the schedule. The summons, while not yet a formal recall, signals a significant downgrade in the bilateral tone that Sheinbaum had worked to maintain.

Political observers in Mexico City noted that Sheinbaum faces a difficult balancing act: reassuring Washington that she remains a functional security partner while managing a domestic constituency that views the indictments as a sovereignty violation. 'She cannot afford to look weak to either audience,' said a senior analyst at CIDE, Mexico's public policy research centre. 'Friday will define whether she controls this story or the party factions do.'
