Chuck Totto, executive director of the Honolulu Ethics Commission, is on leave following an internal personnel investigation. The commission received a complaint regarding Totto’s management of staff and hired an independent investigator.

Totto has been the executive director for over a decade, but has publically struggled to get along with Mayor Kirk Caldwell and his appointees on the commission for the past three years. Conflict emerged in 2013 when Totto investigated the mayor’s inaugural luau, an event largely funded by lobbyists and city contractors.

Totto has been on leave since March 1 and is expected to return on April 4.
