Michigan Gov. Rick Snyder said on Friday that he wants to testify in front of the House Oversight and Government Reform Committee about Flint's lead-contaminated water.

Snyder's official Twitter account stated the embattled governor asked committee Chairman Jason Chaffetz, R-Utah, for the opportunity to come testify in front of the committee. No date for his testimony has been announced.

It's rare for a sitting governor testify before Congress, rarer still for a sitting governor to ask to testify. Snyder has been under fire in recent months for his administration's slow response to the water crisis in Flint.

Snyder said he called Chaffetz on Thursday to ask if he could testify at a future hearing date on the water crisis. He said the people of Flint have been failed at all levels of government.

"In Michigan we are learning a great deal from this crisis and I am hopeful the federal government also will use this as an opportunity to examine health and safety protections in place, assess infrastructure needs, and avoid this type of crisis in the future," he said.

Rep. Elijah Cummings, the top Democrat on the committee, told the Washington Examiner on Wednesday that a decision would be made by the end of the week on the decision to ask Snyder to testify. Instead, it appears Snyder is willing to come on his own.

Snyder declined an invitation to testify in front of the House Democratic Policy and Steering Committee earlier this week.

Shortly after Snyder's announcement Friday, Chaffetz said his committee would hold another hearing on the Flint water crisis at an unannounced date.

In addition to Snyder, Environmental Protection Agency Administrator Gina McCarthy, former Flint Mayor Dayne Walling, former Flint Emergency Manager Darnell Earley and former EPA Region 5 Administrator Susan Hedman will be called to testify.

EPA researcher Miguel Del Toral and Virginia Tech researcher Marc Edwards, both of whom were instrumental in identifying the crisis, will testify as well.

"We are committed to investigating the failures in Flint. We appreciate Governor Snyder's willingness to appear before the committee and look forward to hearing from EPA Administrator McCarthy as well," Chaffetz said. "Their perspectives on this issue are important as we seek to ensure a crisis of this magnitude never occurs in another American city."
