DETROIT (AP) — A federal judge is giving Tesla CEO Elon Musk until March 11 to show why he shouldn’t be held in contempt of court.

The Securities and Exchange Commission asked a federal judge on Monday to hold Tesla (TSLA) CEO Elon Musk in contempt for violating a settlement deal reached last year.

Musk tweeted on February 19 that “Tesla made 0 cars in 2011, but will make around 500k in 2019.” Hours later, Musk sent a follow-up tweet indicating that the company will actually deliver just 400,000 cars this year.

Although Musk corrected his mistake, regulators scolded Tesla’s billionaire CEO because he “once again published inaccurate and material information about Tesla to his over 24 million Twitter followers,” according to court papers filed Monday.

The SEC noted that he did not ask for or receive company approval before publishing his tweet.
