According to Press TV, protesters massed outside the venue of Republican presidential debate at the Fox Theater in Detroit on Thursday night.
In one rally, people condemned lack of attention of GOP presidential candidates to a water issue in Flint, Michigan.
Residents in the US city have for long been suffering from polluted water. Despite distribution of bottled water by National Guard forces, Flint citizens are still unable to live a normal life due to lead-contamination there.
Back in January, President Barack Obama declared a state of emergency in Flint, but the issue remains unresolved.
The protesters called for the resignation and arrest of Michigan Governor Rick Snyder. Flint switched from Detroit’s water system to Flint River in 2014 to save money; however, state officials failed to order local authorities to treat the water with anti-corrosive chemicals and that caused lead to leach from aging pipes into some homes.
Meanwhile, demonstrators in another rally called GOP attention to economic issues such as the minimum wage problem.
