'We're like second-class citizens': Flint's struggle continues as Obama visits

As the water crisis enters its third year, the president is on his way to the city following a letter from an 8-year-old - but some say his visit is overdue

Since 12-year-old Flint resident Jeremiah Loren contracted a debilitating bacterial infection that has rankled his stomach, his grades have dropped dramatically, he's missed four months of school this year, and there are days he doesn't even get out of bed.

Jeremiah, who has tested positive for elevated blood lead levels, first contracted the infection a few months after Flint switched its water supply to a corrosive local river. His mother, Tammy Loren, attributes his illness directly to the Michigan city's contaminated water supply.
