Bill Gates ratcheted up his feud with Elon Musk on Thursday, saying the former DOGE head was "killing" children through USAID cuts.

Driving the news: Gates vowed to give away "virtually all" of his wealth through the Gates Foundation over the next two decades, he announced Thursday.

Gates' "key aspirations" to guide the foundation's funding over the next two decades center on promoting child and maternal health and fighting infectious diseases and poverty.

Those target areas overlap with the USAID programs from which Musk and the Trump administration cut billions.
