The head of the US Environmental Protection Agency, Scott Pruitt, has vowed to save a city that's water supply is contaminated by lead.

Pruitt visited East Chicago in Indiana on Wednesday, where residents have been forced from their homes.

But environmental groups say Pruitt's visit is merely a show-stop, with the agency facing major budget cuts under President Donald Trump.

Al Jazeera's John Hendren reports from East Chicago, Indiana.
