Democratic presidential candidate Cory Booker says it's time to overhaul environmental policies that he says unfairly disadvantage minority and impoverished communities.

The New Jersey senator is promoting what he calls his environmental justice agenda during a campaign stop in South Carolina. He told students at Allen University in Columbia that the government hasn't done enough to ensure all Americans have equal access to clean, healthy communities.

Booker says addressing environmental inequality is one of today's civil rights battles. Booker wants to strengthen Environmental Protection Agency and reverse what he says are Trump administration rollbacks of environmental safeguards.
