Trillionaire Elon Musk spent Monday night posting and re-sharing posts online in an apparent effort to defend his record spearheading massive cuts to U.S. foreign aid " which reporting increasingly suggests may end up causing millions of preventable deaths " and was subsequently hammered by critics. "Musk killed millions by abruptly stopping food and medical supply shipments," wrote Nick Mark, a podcast host and Washington-based physician. "At the time he gleefully celebrated feeding [the U.S. Agency for International Development] (USAID) to the woodchipper' by waving a chainsaw around high on ketamine. Now he's in damage control mode. This is his legacy. Don't let him off the hook."
