(CNN) -- State Attorney General Jerry Brown will announce a development Wednesday in the investigation of high salaries of several leaders of the small California city of Bell.
The revelation earlier this year that a leader of the city of 36,000 people made more than the president rocked the southern California town and made national news.
The outrage about the high salaries prompted the resignation of three city officials. City Manager Robert Rizzo, Assistant City Manager Angela Spaccia, and Police Chief Randy Adams, who reportedly had a combined salary of more than $1.6 million, resigned in July.
But by then Brown had announced that he was investigating the issue.
A statement from Brown's office said that at a news conference Wednesday he plans "to announce a major new development in his investigation into excessive salaries in the city of Bell, as well as the expansion of his probe into excessive compensation paid to officials in other jurisdictions."
Brown, who is running for governor, has said he subpoenaed hundreds of records from Bell as part of the investigation to determine whether civil or criminal action should be taken against any city leaders.
Brown said most city council members in Bell are paid some $100,000 for their part-time positions, citing a Los Angeles Times investigation -- which initially reported on the salaries.
"These outrageous pay practices are an insult to the hard-working people of Bell and have provoked righteous indignation in California and even across the country," Brown said earlier this year.
