Musk was responding to director of the UN's World Food Programme, who told CNN last week that $6 billion from people like Musk and Jeff Bezos could "help 42 million people" who he said "were literally going to die if we don't reach them". 

In a Tweet out this weekend, Musk challenged the UN's statement, saying that if the World Food Programme could provide him "open sourced accounting" on how the $6 billion would be used, he would sell Tesla stock "right now and do it".

Because we all know how important open sourced accounting is to Musk...

Musk demanded that the public "see precisely how the money is spent", he wrote on Twitter.

The WFP's David Beasley responded to Musk, according to Insider, by saying:

"I can assure you that we have the systems in place for transparency and open source accounting. Your team can review and work with us to be totally confident of such."

He clarified that $6 billion wouldn't "solve world hunger", as Musk wrote on his Twitter, but would rather be a "one-time donation to save 42 million lives during this unprecedented hunger crisis."

Beasley has been spending much of his time on Twitter making the case that billionaires should chime in and help world hunger.
