What concerns have been raised about Elon Musk's claims regarding Social Security payments?

Elon Musk has claimed that tens of millions of dead Americans are receiving Social Security payments, but critics argue this information is being shared inappropriately through social media rather than through official channels. Government accountability advocates are calling for proper verification of these claims through formal testimony, suggesting Musk should appear before Congress under oath to provide evidence for his assertions. The concern is that serious allegations about government waste are being communicated in an informal and potentially irresponsible manner, without transparency or accountability.
