accepting campaign contributions from staff and making improper campaign expenditures

In 2019, Huizenga was accused of accepting campaign contributions from staff and making improper campaign expenditures. In August that year, the Office of Congressional Ethics recommended further review by the House Committee on Ethics. In 2024, the Committee closed the matter saying "Based on the totality of the circumstances, including the lack of any clear pattern of misspending or intentional circumvention of any standards of conduct, as well as Representative Huizenga’s consistent cooperation with this review, the significant remedial steps that his campaign has undertaken, and the widespread need for updated guidance on the personal use of campaign funds, the Committee determined that Representative Huizenga’s conduct did not merit a sanction."
