The chief of the Securities and Exchange Commission’s Office of Whistleblower will resign from his post in late July, the federal agency announced Friday evening.

Sean McKessy, the first leader of the five-year-old initiative, oversaw the review of all tips from whistleblowers. McKessy reviewed more than 14,000 tips from all 50 states, the District of Columbia and 95 foreign countries. Under his leadership, the office awarded more than $85 million to 32 people who flagged others’ inappropriate actions to his agency.
