(Reuters) - Billionaire Elon Musk said on Wednesday he was entering Twitter Inc's San Francisco office, days ahead of a court-ordered deadline to close his $44 billion deal for the social media platform.

Musk tweeted, "Entering Twitter HQ – let that sink in!"

Earlier in the day, Musk teased being the top boss of Twitter, after he updated his profile's bio to "Chief Twit".
