Elon Musk to address Twitter staff during Friday visit

Elon Musk, the world’s richest man, changed his public profile descriptor to “Chief Twit” on Twitter, and is visiting the social network’s San Francisco office this week ahead of a court-imposed deadline to buy the company by Friday.

The company is expected to come under Musk’s ownership by 5 p.m. New York time on Oct. 28, as lawyers and bankers on both sides race to finalize paperwork. Leslie Berland, Twitter’s chief marketing officer and head of people, sent a memo to employees Wednesday saying that Musk was visiting the company’s headquarters this week, according to people who received the note.
