National and local NAACP leaders are planning to reveal what they call a "15-point priority plan" to address the health emergency in Flint due to lead-tainted water.

A meeting is scheduled Tuesday in Flint with the National Association for the Advancement of Colored People President and Chief Executive Cornell Brooks, along with NAACP leaders from Flint and Detroit.

The civil rights organization says the plan was developed with input from Flint residents. More than half of Flint's 100,000 residents are black.

Flint switched from Detroit's water system in 2014 while under state emergency management and began drawing from the Flint River to save money.

But the water wasn't properly treated for corrosion, and lead began leaching from aging pipes into the drinking water.

Michigan's Republican attorney general has named a former prosecutor to spearhead an investigation into the process that left Flint's drinking water tainted with lead.

Democrats question whether the special counsel would be impartial.

Attorney General Bill Schuette said Monday that Todd Flood, a former assistant prosecutor for Wayne County, will lead the probe and be joined by Andy Arena, a retired head of Detroit's FBI office.

It is unclear at this point if the probe could result in criminal or civil charges.

The investigation could focus on whether environmental laws were broken or if there was official misconduct in the process that left Flint's drinking water contaminated.
