Elon Musk said he¡¯s terminating his $44 billion agreement to acquire Twitter Inc. and take it private, triggering a legal fight with the company.

Twitter has made ¡°misleading representations¡± over the number of spam bots on the social network, and hasn¡¯t ¡°complied with its contractual obligations¡± to provide information about how to assess how prevalent the bots are, Musk¡¯s representatives said Friday in a letter to Twitter as part of a regulatory filing.

Twitter said it will fight back in court.
