Brooks confirmed in an email that his Twitter account didn’t get hacked. Brian Brooks declared on Twitter on Friday afternoon that he’s resigned as Binance.US CEO after just four months having the title on the job. In the tweet, Brooks said that “differences over strategic direction” between him and his colleagues.

Before joining the U.S. arm of the Binance global crypto exchange, Brooks had the wheel of the Office of the Comptroller of the Currency (OCC). And also the regulator for national banks, under U.S. President Donald Trump.

Brooks and Binance.US

Brooks’ hiring looks like to be a part of a strategy by Binance.US and its parent to make better their standings. Doing that by hiring well-regarded former regulators from around the world. But now, Brooks’ sudden leave, along with last month’s similarly unexpected quitting of the director of Binance Brazil after only six months, is bound to enhance questions as regulatory scrutiny of the world’s biggest crypto exchange by trading volume and its various subsidiaries has only exacerbated. In these past months, multiple countries as well as the U.K. and Japan have taken action against Binance.

In a statement, Binance CEO Changpeng “CZ” Zhao (Binance.US’ chairman) said he is “confident in Binance.US’s business and its commitment to serve its customers.” Brooks’ leave, CZ added, would not affect Binance.US clients “in any way.”

Brooks’ successor

Neither he nor Brooks made it clear that why they parted ways. No word on a successor, even an interim one, either.

“Brian’s work for Binance.US has been invaluable and we hope he will continue to be an integral part of the crypto industry’s growth, advocating for regulations that move our industry forward,”. This was what Zhao said in a separate statement. “We wish him the very best in his future endeavors.”

That well-wishing contrasted with the way Binance.US treated with Brooks’ predecessor Catherine Coley. The exchange didn’t even named her when it hired Brooks in April.

In addition, during his time as acting a controller of the currency, Brooks followed an aggressively crypto-friendly reform agenda and met often with members of the digital asset industry, from corporate CEOs to bleeding-edge entrepreneurs from the decentralized finance (DeFi) space.
