Darryl Forté announced on Twitter late Friday that he has submitted an application to become the interim sheriff of Jackson County.
Forté retired as Kansas City's police chief in May.
He is vying to temporarily fill the role held by Mike Sharp, who hastily resigned earlier this month amid allegations that he had a financial and sexual relationship with an employee at the Sheriff's Office.
The employee, hired at $10 per hour, became the highest-paid civilian employee. She received raises and promotions that were approved by Sharp, according to records.
Forté did not immediately respond to a request for comment late Friday.
County Executive Frank White has the authority to name an interim sheriff, according to the county charter. But one week ago he announced the formation of a nine-member nominating committee, after some county legislators insisted they have an advisory role in the selection process.
In November, voters will choose a successor to fill out the remaining two years of Sharp's term.
He spent more than 30 years in law enforcement, including his last five and a half as KC's chief.
