DENVER (AP) - The oil and gas industry in Colorado is getting a critical look from state lawmakers, some of whom voted Thursday to curb the industry's sway on the commission that regulates drilling.

A bill approved by a Democratic House committee Thursday would prevent people who are currently working for oil and gas companies to also serve on the Colorado Oil & Gas Conservation Commission. The move would be a dramatic turnaround for a commission that is tasked with both promoting drilling and keeping the public safe from its negative effects.

Supporters of the bill say that it's a conflict of interest to ask people to vote on policies that affect their employers. A stream of industry representatives and mineral-rights owners argued that oil and gas workers have valuable expertise.
