It's been a tumultuous weekend for USAID -- the U.S. Agency for International Development. On Saturday sometime after 3 a.m., its website went down, according to the Internet Archive, a nonprofit group that tracks web pages. Some browsers display the error message: "This site can't be reached. Check if there is a typo in www.usaid.gov." The agency's account on X (formerly Twitter) has also been deleted. Then on Sunday, Elon Musk wrote on X that USAID is a "criminal organization."
