Trump did that, not Elon. The president is the only one with the power to cut that aid. Sure, he was the "face" of it but Trump signed the EOs
Elon actually bragged about destroying USAID on Twitter.
"We spent the weekend feeding USAID into the wood chipper. Could gone to some great parties. Did that instead."
This is the richest man in the world being GLEEFUL abut destroying an organization that helps the poorest people in the world. Musk is basically Ebenezer Scrooge.
In an interview when asked about it he insisted their was vast amounts of fraud in USAID.
Elon proposed it and implemented it. Yes, Trump signed off on it but by that logic no one in the Trump administration is guilty of anything other than Trump himself, which we all know is not true.
