Some Flint residents are expected to attend a U.S. House committee hearing on the city's lead-tainted water crisis.
The community group Flint Rising and the AFL-CIO say members of five families will be present Tuesday in Washington when Flint's former state-appointed emergency manager Darnell Earley is expected to testify.
Gov. Rick Snyder and Environmental Protection Agency chief Gina McCarthy also are expected to testify.
Earley was heading Flint's finances when a decision was made to switch from Detroit's water system to the Flint River.
The switch was made in 2014 to save money until a new pipeline to Lake Huron was ready. The corrosive water leached lead from the city's old plumbing because certain treatments weren't added to the water.
Tests later showed high lead levels in some children.
