DETROIT, MI -- U.S. Rep. Brenda Lawrence (D-Southfield) said Wednesday that a congressional hearing she requested on the Flint water crisis has been scheduled for Feb. 3, but that it won't include testimony from Gov. Rick Snyder.

Lawrence said Snyder was at the top of a list of witnesses she wanted to question in the hearing of the House Committee on Oversight and Government Reform.

But when she received notice Wednesday of the hearing being scheduled, it was clear that Snyder would not be called to testify, Lawrence said.

"I am deeply disappointed at the Majority's lack of commitment to a thorough and meaningful hearing," said Lawrence, ranking member of the Subcommittee on the Interior, in a statement.

"A sincere search for truth and justice requires a full review by the entire Committee of the decisions and policies of all those involved. The nearly 100,000 people of Flint who have been permanently impacted by this crisis, either directly or indirectly, demands that Congress set aside party politics if we are to ensure that this never again occurs in Flint or any city in America."

It wasn't yet clear who will be called to testify at the Feb. 3 hearing.

Lawrence said she asked to hear from Snyder, former Michigan Department of Environmental Quality Director Dan Wyant, Environmental Protection Agency Regional Director Susan Hedman, Hurley Medical Center doctor Mona Hanna-Atissha, Flint Mayor Karen Weaver and Virginia Tech Professor Mark Edwards.

"The only way that we can hope to earn back the shattered trust of the American public is for our government leaders to put the needs and interests of the people we serve above all else," Lawrence said.

The hearing is being called in response to the uproar over elevated lead levels discovered in the blood of children after a change in Flint's water system.

The city, while under state-controlled emergency management, switched its water source to the Flint River in April 2014, while under control of a state-appointed emergency manager.

Flint reconnected to Detroit's water system in October 2015 after doctors at Hurley Medical Center alerted the community to dangerous lead levels.

Despite the switch back, the state is still advising Flint residents not to drink unfiltered tap water coating inside pipes may have been damaged by the highly corrosive water that flowed during the period in which the Flint River was the source.

The National Guard and volunteer groups have been distributing water filters and bottled water to residents.

The state and the White House have issued official emergency declarations over the Flint crisis.

Federal investigators and the state attorney general are probing the circumstances and interactions that led to the crisis.
