Elon Musk has announced that he is temporarily pausing his takeover of the social media outlet Twitter.

Why is the Tesla CEO making this decision? According to Musk, the decision comes after he questioned its number of users.

“Twitter deal temporarily on hold pending details supporting calculation that spam/fake accounts do indeed represent less than 5% of users,” Musk tweeted.

Musk announced last month he would purchase Twitter, turning the company from a publicly owned business to one controlled by Musk.
