As violent unrest erupted in western Mexico following the death of a top cartel boss, Markwayne Mullin has urged American spring breakers to rethink or cancel their plans to travel to Mexico. He warned that the situation remains unpredictable for tourists.

The Republican senator from Oklahoma made the comments during an appearance on CNBC's Squawk Box, saying anyone planning a holiday in Mexico for spring break should carefully consider their safety, given the recent spike in violence.

What Sparked the Warning?

Mullin's warning comes after the killing of Nemesio Rubén Oseguera Cervantes, better known as 'El Mencho', the leader of the powerful Cartel de Jalisco Nueva Generación (CJNG). This criminal organisation is considered one of Mexico's most dangerous and has been linked to international drug trafficking, including the supply of fentanyl into the United States.

Mexican federal forces carried out an operation in Jalisco targeting El Mencho. His death triggered violent retaliation from cartel members, with reports of vehicles set on fire, blocked roads, and clashes in several states. While authorities later described the situation as stabilised and began reopening transit routes, safety concerns remain.

Mullin's Stern Advice to Spring Breakers

Speaking on Monday, Mullin highlighted that the unrest had created a tense environment. He urged Americans not to travel to Mexico for leisure, citing personal examples.

'Anybody that's planning on going to Mexico for spring break ... my chiropractor called me yesterday and said he's still planning on going to Cancún. I said, 'Are you crazy?' Mullin said. He added that 'no one should be going down there right now' given the volatile situation.

The senator's comments have drawn attention not only for safety reasons but also because they touch on broader political and diplomatic concerns, sparking discussion in both political and travel circles.

Mexican Authorities Respond

Mexican officials have acknowledged the unrest but emphasised that steps are being taken to restore order. The Mexican Embassy in Washington DC said authorities were gradually reopening transportation links and ensuring stability in tourist areas. This, even as some local security measures remain in place.

International flights have resumed, and airports such as Puerto Vallarta International Airport have reopened for domestic services, with broader operations slowly returning to normal.

Travel Advisory Status

Despite reassurances from Mexican authorities, the US State Department's travel advisory for Mexico remains in effect. Earlier this month, Americans in some parts of Mexico were told to shelter in place, though those restrictions have since been lifted.

The advisory continues to reflect concerns about cartel-related violence and its potential impact on foreign nationals, particularly outside established resort zones.

Understanding the Cártel de Jalisco Nueva Generación

Until his death, El Mencho led the CJNG, a sprawling criminal network with operations across much of Mexico. US authorities had placed a multi-million-dollar bounty on him for his role in drug trafficking and violence.

The cartel is considered one of the most dangerous in the region and has been linked to extensive cross-border drug flows and violent confrontations with security forces.

What This Means for Tourists

The aftermath of El Mencho's death has prompted many travellers to reconsider their spring break plans. While some resort areas remain largely operational, Mullin's warning highlights serious safety concerns for American visitors.

With spring break approaching and travel plans often booked months in advance, his comments are likely to intensify discussions about travel safety, tourism, and international security.
