Bono’s ‘300,000 dead’ claim over USAID cuts gets smacked down by Rogan, Musk: ‘Liar/idiot’

U2 frontman and longtime global activist Bono took a swing at the Trump administration disbanding the U.S. Agency for International Development (USAID)) on "The Joe Rogan Experience" podcast, blaming the cuts for a staggering 300,000 deaths.

And he was swiftly fact-checked by Rogan and Elon Musk in a takedown that lit up social media.

Reacting on X to a clip of the conversation, Elon Musk slammed Bono directly.

"He’s such a liar/idiot," Musk wrote.

Musk, who has championed sharp cuts to what he sees as a bloated foreign aid machine, pushed for major USAID reforms under the Department of Government Efficiency (DOGE) before his formal departure this week.

His response ignited debate online, with conservatives cheering for overdue accountability.

Popular online commentator "Catturd" posted that "I agree 100% with Elon Musk that Bono is an idiot and a liar."

One commentator also wrote, "They've made this 300,000 number up and propagandized people with it."

Another eagle-eyed X user posted, "Bono starts off by saying, ‘It’s not proven.’ So he’s lying."

Bono’s 300,000 figure comes not from confirmed deaths, but from a speculative model built by Brooke Nichols, a mathematical health modeler at Boston University, projecting what could happen as a result of the cuts.

Nichols has said that the number is a projection, not a direct count, due to the absence of real-time tracking in many affected regions. 

"The biggest uncertainties in all of these estimates are: 1) the extent to which countries and organizations have pivoted to mitigate this disaster (likely highly variable)," she wrote in The Washington Post. "And 2) which programs are actually still funded with funding actually flowing — and which aren’t."
