Grimes and Azealia Banks have become embroiled in a class action suit by investors against Tesla and Elon Musk, Business Insider reports. A California federal court judge has granted the plaintiffs' motion to serve Grimes, Banks, and others subpoenas for the preservation of documents, meaning they cannot destroy anything that could be considered evidence.

Tesla investors are suing Tesla and Elon Musk over Musk’s infamous tweet where he wrote, “Am considering taking Tesla private at $420. Funding secured.” According to their lawsuit, viewed by Pitchfork, they claim that, due to Musk’s “materially false and misleading statements, as well as their market manipulation,” they “were injured to the tune of hundreds of millions of dollars.”

Plaintiffs asked to subpoena Grimes (aka Claire Elise Boucher) because:

According to the New York Times’ interview [“Elon Musk Details ‘Excruciating’ Personal Toll of Tesla Turmoil”], Ms. Boucher may have been the last person Musk spoke with prior to sending the August 7, 2018 tweet at issue in this lawsuit. According to Ms. Banks (as discussed in the Business Insider article [Rapper Azealia Banks claims she was at Elon Musk’s house over the weekend as he was ‘scrounging for investors’”]), Ms. Boucher was with Musk in the hours and days following the tweet. If, as Ms. Banks claims, Musk was actively attempting to find investors to “cover” for the tweet, then Ms. Boucher likely observed this behavior or overheard conversations between Musk and potential investors. It is also likely that Ms. Boucher, as Musk’s girlfriend, discussed the tweet and/or the fallout caused by it with Musk shortly after it was sent.

Plaintiffs also explained why Banks should be served a subpoena:

Ms. Banks has proven to be a key source of information in this matter. As recounted by Business Insider, she purportedly observed Musk attempting to “cover” for the tweet after it was sent. She was also present in Musk’s home in Los Angeles while Musk was dealing with the fallout from the tweet and likely observed relevant events in addition to those described in the media.

Azaelia Banks has claimed that Elon Musk was “on acid” when he sent the tweets about taking Tesla private. Banks later wrote an open apology letter to Musk.

In addition to being sued by Tesla investors, Elon Musk was sued by the SEC for fraud in September 2018.

When contacted by Pitchfork, Azealia Banks’ representatives offered no comment. Pitchfork has contacted representatives for Grimes.
