"Twitter deal temporarily on hold pending details supporting calculation that spam/fake accounts do indeed represent less than 5% of users," he wrote in his tweet.

Tesla lost $400 billion in market value after Musk announced his interest in buying Twitter, and the entrepreneur said last week that he'd collected more than $7 billion in financing from Oracle founder Larry Ellison, cryptocurrency exchange Binance, the Qatar sovereign wealth fund and Saudi Prince Alwaleed bin Talal.
On Thursday, Twitter announced a leadership shuffle, removing consumer product leader Kayvon Beykpour and Bruce Falck, the company's general manager of revenue and head of product. Jay Sullivan, vice president of consumer product, will take over Falck's roles.
"Effective this week, we are pausing most hiring and backfills, except for business critical roles," Twitter spokesman Adrian Zamora said according to The Verge.
"We are pulling back on non-labor costs to ensure we are being responsible and efficient."
