Daniel Koh, the Department of Labor’s chief of staff, divested his holdings in Amazon on Friday after his personal financial disclosures revealed he owned a significant stake in the e-commerce giant, according to multiple reports.
The financial disclosures, obtained by the Revolving Door Project, showed that Koh owned Amazon shares worth between $100,000 and $250,000.
A Department of Labor spokesperson said Koh sold the shares after his stake was disclosed, news outlet Motherboard reported.
A department spokesperson told the Huffington Post that Koh made his disclosures as required and as "awaiting the standard guidance from DOL's ethics lawyers on potential conflicts of interest."
Koh’s stake represented a potential conflict of interest because the Department of Labor enforces workplace health and safety standards and Amazon has been accused of safety violations.
The Department of Labor did not immediately respond to a request for further comment.
Labor Secretary Marty Walsh tapped Koh to serve as his chief of staff in February. Koh previously held the same post when Walsh was mayor of Boston.
