The US State Department's website prematurely announced that President Donald Trump had left office Monday, sending social media into a tailspin on what happened. "Donald J. Trump's term ended 2021-01-11 19:49:00," Trump's official biography page said briefly on Monday before being taken down, with internet users instead seeing a message that there was a technical error. The State Department did not immediately respond to a question on whether the incident was the result of hacking or a glitch. But it appeared clear that Trump -- who remains president on the White House website -- had not found an uncharacteristically subtle way to quit through a hard-to-find page.
