Elon Musk visits Twitter headquarters ahead of takeover deadline

"Entering Twitter HQ – let that sink in!" said the caption of a video that Musk tweeted in which he was walking into the Twitter office carrying a sink in his hands. Hours earlier, he hinted at being the company's top boss after updating his profile's bio to "Chief Twit". Twitter confirmed Musk would visit the San Francisco office this week, but declined to comment further.
