Tesla Inc said Monday it received a subpoena from the US Securities and Exchange Commission in connection with a settlement requiring Chief Executive Elon Musk's tweets about relevant company information to be verified.

The Securities and Exchange Commission issued the subpoena on November 16, roughly ten days after Musk asked his Twitter followers whether he should sell 10% of his share in the firm, precipitating a stock selloff.

As of a recent close, the electric vehicle manufacturer's stock had plunged roughly a quarter in response to the tweet. On Monday morning, the shares were down 1.4 percent to $909.98.

The SEC's latest move, which Tesla reported in a securities filing, adds to Tesla's pressure from federal auto safety regulators over vehicle recalls and probes into its driver-assistance software. The SEC did not respond to a request for comment.

Musk settled an SEC lawsuit in 2018 over a tweet about taking the company private, agreeing to have tweets containing relevant information about the company pre-approved by the firm's lawyers.

Tesla was sued in December over Musk's social media posts, notably his Twitter poll on stock sales, which sent the company's share price down. This was not the first lawsuit filed against Musk alleging that he violated the settlement terms.

According to Reuters, the SEC started an inquiry last year into a whistleblower complaint that Tesla neglected to adequately disclose to shareholders and the public over multiple years about fire hazards related to solar panel system faults.

Tesla stated Monday that the company cooperates with government subpoenas and other investigations and inquiries "routinely."

Additionally, the company stated in the filing that the California Department of Fair Employment and Housing conducted an investigation into allegations of race discrimination and harassment at Tesla locations and informed the company that it has grounds to file a civil complaint against the electric-car maker.

Tesla has already faced several lawsuits alleging racial abuse and sexual harassment, and a federal jury awarded the corporation $137 million in one of the instances in October.

The New York State Common Retirement Fund announced Monday that it had sent shareholder recommendations to Tesla, Activision Blizzard, and Starbucks Corp, urging that they report on their efforts to avoid workplace harassment and discrimination.

The plans require corporations to disclose, among other things, the overall number and aggregate monetary amount of sexual abuse, harassment, and discrimination-related complaints resolved.

Tension between Musk and the White House

In recent months, Tesla and the White House have been at odds, with the Biden administration focused on traditional automakers such as Ford Motor Company and General Motors in the electric vehicle competition.

The CEOs of General Motors and Ford attended a conference of technology and auto businesses sponsored by US Vice President Joe Biden last month. Musk was not on the guest list.

Musk has been attacking the Biden administration on Twitter for supposedly neglecting Tesla and praising Detroit automakers as pioneers in the transition to electric vehicles. Musk recently referred to Biden as a "damp sock puppet" in a tweet.

Musk is also at odds with the United Auto Workers (UAW), a key Biden ally. In March, the National Labor Relations Board ordered Musk to delete a tweet in which he stated that Tesla employees would lose stock options if they voted to join the United Auto Workers. Tesla has filed an appeal against the order.

Tesla stated Monday that the fair market value of its bitcoin assets as of December 31 was $1.99 billion.

The corporation, which invested $1.5 billion in bitcoin last year before selling 10% of its position, said it recorded around $101 million in impairment losses owing to bitcoin's value decline last year.
