Elon Musk posted a video of himself entering Twitter's San Francisco headquarters carrying what appears to be a bathroom sink on Wednesday.

The video shows the billionaire laughing and talking to someone out of view of the camera. Musk captioned the video: "Entering Twitter HQ — let that sink in!"

Earlier on Wednesday, Twitter Chief Marketing Officer and Head of People Leslie Berland sent out an email notifying employees that Musk would be in the office over the course of the week, a source who received the email told Insider.

Hi Team, As you'll soon see or hear, Elon is in the SF office this week meeting with folks, walking the halls, and continuing to dive into the important work you all do. If you're in SF and see him around, say hi! For everyone else, this is just the beginning of many meetings and conversations with Elon, and you'll all hear directly from him on Friday.
I'll be in the SF office shortly too, excited to see all of you!

Musk also changed his bio on Twitter to "Chief Twit" on Wednesday. Earlier this week, the Tesla CEO said on Twitter that he has been back to "spare bedroom/couch surfing at a friend's house in Silicon Valley."

The billionaire has until Friday to close the deal. Earlier this month, the Delaware judge overseeing the court case gave the two parties until 5 p.m. ET on October 28 to agree to a new deal or the case will resume in a five-day trial in November.

On Tuesday, Bloomberg reported that the banks in charge of the debt-financing are in the process of signing the documents and Musk had promised the deal would close by Friday.
