Following just four months as CEO, Brian Brooks resigned from Binance.US on Twitter. As Brooks pointed out in the tweet, he and his colleagues disagreed on the strategic direction.
Brooks, who joined the U.S. arm of Binance, formerly headed the Office of the Comptroller of the Currency (OCC), the regulator of national banks.
As part of Binance.US's strategy to improve its standing, Brooks was hired by the company and its parent company along with numerous other former regulators from around the world.
The sudden departure of Brooks, which took place just six months after another unexpected departure of the director of Binance Brazil, has prompted questions as regulators have become increasingly critical of the world's largest crypto exchange by trading volume and its numerous subsidiaries.
In the U.S., the company is named after the world's largest cryptocurrency exchange, Binance Holdings Ltd.
A U.S. government investigation is underway against Binance Holdings. It is being investigated by the Justice Department for potentially facilitating money laundering or tax evasion. Binance affiliate operations within a number of countries have also been investigated and halted.
Changpeng "CZ" Zhao (chairman of Binance.US) further expressed "confidence" in the company's business and commitment to serving its customers.
Neither CZ nor Brooks provided any further details as to why they parted. As of yet, there is no successor, not even a temporary one.
Chairman of Binance.US, had earlier stated that he would step down once a replacement is identified, that the company would make changes to obtain licenses in several jurisdictions, and that regional leaders would be appointed.
