But earlier this month, Musk withdrew his offer. Twitter reacted by bringing a legal case against Musk to force him to buy the company. Legal experts say Twitter wants to complete the deal that both sides agreed to. The company said Musk's reasons for backing out are just a cover for changing his mind. In April, Musk offered to pay $54.20 a share for Twitter. The company accepted the offer after opposing the sale earlier. Musk accused Twitter of not giving him enough information about how many spam accounts appear on the service.
