In July, Twitter sued Musk, who is also chief executive of electric vehicle maker Tesla Inc to hold him to his April agreement to buy the company for $54.20 per share. The company has alleged that Musk got cold feet over the deal as global politics and inflation rattled markets soon after the deal was signed.
At Tuesday's hearing, Twitter's lawyer read a message from Musk that came to light during the litigation that the lawyer said showed the billionaire was not actually concerned about spam accounts.
Musk sent a message to a Morgan Stanley banker in May, as Russia's President Vladimir Putin was warning the West over his country's war in Ukraine, that read "it won't make sense to buy Twitter if we're heading into World War III." The deal contract allows Musk to walk away under certain narrow conditions, although a war is specifically excluded.
