Sen. Ed Markey (D-Mass.) on Sunday threatened Elon Musk to "fix" his companies "or Congress will," hours after Musk mocked the senator for demanding answers about Twitter's verification process.
Driving the news: The exchange comes days after Markey tweeted to Musk, attaching a letter, demanding Twitter to explain how a Washington Post reporter was able to successfully set up a verified account impersonating the senator.
After laying off half its staff earlier this month, Twitter on Saturday started culling its vast ranks of contract staff, sources confirmed to Axios.
Why it matters: Like many companies, Twitter's staff is made up of a mix of full-time employees as well as contract workers who work for a third party.
Elon Musk is using the same leadership playbook at Twitter that he has at his other companies. It's proving to be a costly mistake.
What to know: Musk has a well-earned reputation for being among the most demanding and capricious bosses in the history of corporate America. Past and present employees tell of being assigned tasks with cost or timeline objectives that seem impossible, often with their jobs hanging in the balance.
