Hickenlooper on climate change

Former Colorado Gov. John Hickenlooper defended his record on regulating oil and gas companies and fighting climate change on Wednesday, saying he would put his record on the issue up against anybody else.

Hickenlooper, a former geologist, has been criticized from the left for his efforts to regulate the oil and gas industry in Colorado, arguing that he has not gone far enough and worked too closely with the industry to craft regulations.
