Democrats eyeing 2020 spar with EPA's Andrew Wheeler over climate change 'crisis'

Democrats with 2020 presidential ambitions sparred with Environmental Protection Agency acting Administrator Andrew Wheeler on Wednesday, begging him to fight the climate change “crisis” and stop weakening regulations intended to address the problem.

“How does it happen that the nominee of the head of the EPA does not mention the words ‘climate change’ when the environmental community thinks it is the greatest crisis facing the planet?” said Sen. Bernie Sanders, I-Vt., a likely 2020 presidential candidate, noting that Wheeler did not mention climate change in the opening statement of his confirmation hearing.
