Mexico's President Claudia Sheinbaum proposed a constitutional amendment to bar dual citizens from running for president, drawing immediate criticism from billionaire Ricardo Salinas, a potential rival. The measure would also apply to candidates for governor in Mexico's 31 states and mayor of Mexico City. Under the plan, anyone with another nationality must renounce it before registering as a candidate.

Salinas, who holds dual citizenship, called the move a political maneuver.
