Obama visits Flint as questions linger on EPA role in water crisis

By Timothy Gardner WASHINGTON (Reuters) - President Barack Obama on Wednesday will visit Flint, Michigan, a city struggling with the effects of lead-poisoned drinking water, as questions linger over whether his environmental regulators could have acted more urgently to address the crisis. Obama will get updates from federal officials on the response in Flint, a mostly African-American city where more than 40 percent of the city's 100,000 people live in poverty. "Like you, I'll use my voice to call for change and help lift up your community," Obama wrote last week to Amariyanna Copeny, an eight-year-old Flint girl who has marched in protests about the crisis and had asked to meet him.
