Twitter has begun widespread layoffs as new owner Elon Musk overhauls the company. The move has raised grave concerns about chaos enveloping the platform as a source of reliable information just days ahead of the U.S. midterm elections. The speed and size of the cuts also opened Musk and Twitter to lawsuits. At least one was filed in San Francisco alleging Twitter has violated federal law by not providing the required notice. The company had told employees by email that they would find out Friday if they had been laid off. Yoel Roth, Twitter’s head of safety and integrity, confirmed on Twitter the cuts affected about half of the company’s staff of 7,500.
