FIRST ON FOX: United States Senator Tim Sheehy, R-Montana, called out Mexican president Claudia Sheinbaum in a scathing letter addressing the large amount of raw sewage and waste the neighboring country has dumped in the Tijuana River.
The letter outlines Sheehy’s concern not only for the health and safety of local residents, but also points out that the toxic leak could potentially be jeopardizing U.S. national security.
“This continuous discharge is sickening thousands of Americans annually, including U.S. Navy SEALs and Marine special forces who train in the affected waters,” the letter to the president of Mexico reads. “In February 2025, the Department of Defense Office of Inspector General concluded that, absent action, Navy Special Warfare Command would be advised to cancel or relocate up to 75 percent of water training exercises at Naval Amphibious Base Coronado due to elevated bacterial contamination levels.”

Last week, the International Boundary and Water Commission stated that Mexico is dumping 5 million gallons of sewage a day into the Tijuana rRver. The toxic waste then flows up into the United States, and can even make its way into the Pacific Ocean.
“For decades, Mexico has been dumping toxic waste into the water where our most elite servicemen train, causing serious health issues and harming our readiness,” Sheehy told Fox News Digital. “The problem is only getting worse, and their failure to do anything about it is harming our troops and our national security. Mexico needs to put a stop to this toxic tide immediately.”
While Sheehy is sounding the alarm from Congress, local leaders have also confirmed that the Mexican government’s intentional waste dump has left residents with dangerous and harmful environmental conditions.

“This sewage isn’t just disgusting — it’s dangerous. It contains E. coli, antibiotic-resistant bacteria, arsenic and other toxic chemicals,” San Diego County Supervisor Jim Desmond explained in a recent Fox News op-ed. “Our water is contaminated. Our air is polluted with aerosolized waste. Residents are reporting everything from skin infections to viral pharyngitis — and even family pets have gotten sick after exposure.”
Next Tuesday, Fox News Digital reported that EPA Administrator Lee Zeldin is very aware of the issue, and intends to visit a local treatment facility in San Diego to assess the harmful flow of poisonous waste entering the U.S. from Mexico. A source close to Zeldin told Fox that this is a top priority for President Donald Trump’s environmental leader.

“We have heard far too many horror stories of Navy SEALs – some of the bravest and brightest service members in the military – falling ill from training in waters that have been contaminated by Mexican sewage that has flown into our nation,” Zeldin told Fox on Friday. “This has been a human health crisis that has lingered for decades.”
