FLINT, Mich. (AP) -- Michigan's attorney general is expected to file new criminal charges related to Flint's lead-tainted water crisis.
Attorney General Bill Schuette's probe with Genesee (JEN'-uh-see) County Prosecutor David Leyton has already led to charges against 13 current or former government officials, including two city emergency managers appointed by Gov. Rick Snyder.
Two defendants pleaded no contest to willful neglect of duty. The other cases are pending.
Schuette is planning a news conference in Flint Wednesday morning.
Flint started using untreated Flint River water to save money in 2014, resulting in lead being leached from pipes into the water supply. It returned to Detroit's water system in 2015.
Flint's water has improved, but residents will be using bottled water or faucet filters for years until thousands of lead pipes have been replaced.
