Gov. Rick Snyder is asking the federal government to expand Medicaid coverage to people under 21 and pregnant women who have been exposed to Flint's lead-contaminated water.
In a statement released Sunday, Snyder says about 15,000 more Flint residents would benefit if the government approves the request.
The governor says the state would help by lining up doctors and behavioral health specialists and providing other services.
For 18 months, Flint used the Flint River for drinking water.
