Environmental Protection Agency (EPA) Administrator Gina McCarthy is appearing at three Capitol Hill hearings to answer questions about the mine waste spill in Colorado that her agency has taken responsibility for.
The hearings are part of an effort by lawmakers to figure out what went wrong at the Gold King Mine and afterward, who is responsible and how the EPA can prevent it from happening again.
Republicans have attacked the EPA as incompetent and accused officials of holding themselves to a different standard than what they expect of private companies.

Interior Secretary Sally Jewell and McCarthy will appear, along with representatives of the Navajo Nation and the Southern Ute Indian Tribe.
Later Wednesday, the Senate Indian Affairs Committee with grill McCarthy on the effects of the spill on downstream American Indian communities. Navajo and Southern Ute representatives will speak at the hearing as well.
