Gavin Kliger helped oversee mass firings at the Consumer Financial Protection Bureau while holding stock in companies that experts say likely stand to benefit from dismantling that agency — a potential violation of federal ethics laws.

Gavin Kliger, a 25-year-old Department of Government Efficiency aide, disclosed the investments earlier this year in his public financial report, which lists as much as $365,000 worth of shares in four companies that the CFPB can regulate. According to court records and government emails, he later helped oversee the layoffs of more than 1,400 employees at the bureau.

Ethics experts say this constitutes a conflict of interest and that Kliger’s actions are a potential violation of federal ethics laws.

Executive branch employees have long been subject to laws and rules that forbid them from working on matters that “will affect your own personal financial interest.” CFPB employees are also required to divest from dozens of additional, specific companies that engage in financial services and thus either are or could be subject to agency supervision, rulemaking, examination or enforcement.
