US security regulators have been reluctant to take Elon Musk back to court over Tesla Twitter posts, documents show

• The Securities and Exchange Commission has not taken Musk to court to enforce a 2018 agreement since a judge’s 2019 remarks telling the parties to ‘work this out’
• Musk did not have dozens of tweets about Tesla vetted before posting, as he agreed to four years ago, as lawyers said they did not contain material information
