What is USAID and why is Elon Musk trying to kill it?

During the early morning of Monday, Feb. 3, protesters flooded the Washington, D.C. street that marks the entrance to the U.S. Agency for International Development. The group wasn't trying to enter the federal premises in a violent takeover, but rather act as a wall of defense between the government agency and a directive to cease the organization's work as a matter of fiduciary foresight. Later that afternoon, the USAID office shut down. The official USAID website is no longer available. SEE AL
