Governor Gavin Newsom's office has confirmed that California Lottery director Hugo Lopez is resigning and that Friday is his last day with the department he has headed since 2015.

Lottery officials declined to comment and referred questions about the resignation to the governor's office. A spokesman for the governor would not comment on the reason for Lopez's departure but did say a successor is expected to be named soon.

The California Lottery has been under investigation by the Department of Justice ever since the State Controller Betty Yee looked into allegations by an anonymous lottery employee who claimed that lottery executives engaged in lewd and inappropriate conduct at conferences, including one instance in which a lottery official allegedly put his up a woman's shirt. In response to that letter, Yee's office found that lottery staff misspent hundreds of thousands of dollars on travel and hotel accommodations for conferences over four-year period. At least one senior lottery executive has been fired since the investigation was started.
