In light of recent accusations made by a Twitter whistleblower, Elon Musk's lawyers sent a second deal termination letter to Twitter on Monday.

The letter follows up on his initial termination notice last July.

Elon Musk's lawyers seized on the revelations of a Twitter whistleblower last Wednesday, attempting to force the platform to hand over vast amounts of information in their fight to cancel the billionaire's buyout bid.

Musk's lawyers issued a subpoena to Zatko on Monday, requesting "documents and communications" about a number of the alleged wrongdoings claimed by Zatko, including "Twitter's tracking and measurement of user engagement."

In further details, they argue in the new termination letter that Zatko's allegations, "if true, demonstrate that Twitter has breached" a number of provisions from its merger agreement with Musk, most notably its compliance with all laws as well as its claim that it never filed misleading data to securities regulators.

They cite Zatko's claim that Twitter infringed on a 2011 FTC consent decree on user data privacy not to mention "its general obligations under data privacy, unfair trade practice, and consumer protection laws and regulations."

However, the whistleblower complaint does not strictly back Musk's original claim that Twitter violated its contract terms by deceiving investors about the number of spam accounts on its platform and refusing to provide information.

Rather, it claims Twitter misled regulators about its efforts to reduce spam and protect the platform from security threats.

Meanwhile, all eyes are on the judge presiding over the case whether or not he will believe Musk's argument at a hearing scheduled for October in a Delaware Chancery Court.
