• CEO Elon Musk has made some dramatic changes to Twitter since taking over five weeks ago.

• Amid layoffs, firings, and resignations, the billionaire has brought in many new people to Twitter.

• Among them are said to be relatives, fans, and even the conservative commentator Bari Weiss.

A lot has changed at Twitter in about five weeks of ownership by Elon Musk, from the way remaining employees work to how the company seems to bring on new colleagues.

Some of the people spotted at Twitter headquarters in San Francisco lately include people from Musk's orbit of companies like Tesla and The Boring Company, his cousins, and even the commentator Bari Weiss, who is expected to help Musk release his so-called Twitter files.

Roughly 150 people are still working at Twitter at Musk's behest from his other companies and ventures, according to two people familiar with the company. Remaining Twitter employees initially expected this to be temporary as Musk transitioned Twitter to his control, but now some wonder whether "Musk's goons," as several employees refer to Musk's hires and confidants, will remain fixtures at Twitter HQ in San Francisco and how many more will be brought in to work.

About 70% of Twitter's 7,500-member staff have been laid off or fired or have resigned since Musk took over. The company has yet to reveal any kind of formal executive or reporting structure since Musk took over, and the internal employee directory has been down for several weeks, the people familiar said.

A Twitter representative didn't respond to an email seeking comment.

Musk's hires at Twitter

Two of Musk's cousins, James and Andrew Musk, appear to now be acting as full-time Twitter employees, both of the people familiar said. They are sons of Musk's uncle on his father's side. Both men work daily at Twitter offices, with Andrew Musk working on software-engineering projects and James Musk seen more as "a fixer type," one of the people said, helping Musk out with various needs and tasks. Another family member frequently seen around the office is Musk's two-year-old son with Grimes, X Æ A-12, the people familiar said. The toddler is often on the 10th floor, where Musk works and sometimes plays with X amid the many employees now working on that floor as well.
