Government officials in Orange county, California, have warned that an overheated chemical tank “will fail” and could result in a chemical explosion in the area, the Environmental Protection Agency administrator said on Sunday.

Common ground

Zeldin, a former Republican congressman with no prior experience in environmental policy, was chosen by Trump as the head of the EPA.
