LANSING, Mich. (AP) -- 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, though Democrats questioned whether the special counsel would be impartial.
Attorney General Bill Schuette said Monday that Todd Flood, a former assistant prosecutor for Wayne County, which includes Detroit, will lead the probe and be joined by Andy Arena, a retired head of Detroit's FBI office.
Schuette said the two would play key roles in the investigation and prevent conflicts of interest since the attorney general's office also defends the state. Both will report to Schuette, who promised they would provide an "experienced and independent review of all the facts and circumstances."
He dismissed any concerns about Flood, who is now in private practice and has donated to candidates from both parties, including the maximum allowable amount to Schuette.
"I don't care who he (Flood) has given money to, Republican (or) Democrat. It doesn't matter," Schuette said. "This is about conducting a thorough, exhaustive, complete investigation. That's what we're doing."
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.
Flood declined to discuss which laws may have been broken, except to note that "a plethora of laws" could be used and that there are prohibitions against misconduct by public officials.
Schuette gave no timetable for the investigation.
Flint switched from Detroit's municipal water system while under emergency state financial management and began drawing from the Flint River in 2014 to save money, but the water was not properly treated. Residents have been urged to use bottled water and to put filters on faucets.
Republican Gov. Rick Snyder has been a focus of criticism, but Schuette said political affiliations would not be a factor there either.
Democrats noted state records show Flood gave $3,000 to Snyder's campaigns and the maximum $10,200 to Schuette over the 2010 and 2014 election cycles. Flood also gave $1,200 to former Democratic Gov. Jennifer Granholm and donated to various judicial candidates.
State Rep. LaTanya Garrett, D-Detroit, is asking U.S. Attorney General Loretta Lynch to open a federal investigation instead. She noted that Schuette denied a Democratic legislator's September request for a state investigation.
"I am not confident that he can serve in the best interest of the Flint citizens," Garrett said.
Schuette declined to investigate in December but later reversed course and announced the inquiry Jan. 15. That came more than four months after a Virginia Tech researcher said the Flint River was leaching lead from pipes into people's homes because the water was not treated for corrosion.
The attorney general said he continually reviews information that comes his way, and that a mass of new data that came to light around New Year's prompted him to open a probe.
The attorney general's office represents the people of Michigan and the state government, so Schuette said having the special counsel will help prevent conflicts between Schuette's team and those defending the governor and state departments against water-related lawsuits.
Lawsuits against Snyder and the state will be supervised by Chief Deputy Attorney General Carol Isaacs and Chief Legal Counsel Matthew Schneider. Schuette noted there was a similar effort during Detroit's bankruptcy case to avoid conflicts of interest.
Flood represented former Detroit Mayor Kwame Kilpatrick in state court in 2013 when Kilpatrick was accused of violating parole in a case that forced him out of office. Arena heads the Detroit Crime Commission, a nonprofit aimed at reducing criminal activity.
Schuette declined to say how much the outside investigators will be paid.
"This is going to be a 'Joe Friday' investigation," Arena said, referencing the detective from the TV show "Dragnet" known for his factual approach, "so I'm Joe Friday."
