Marco Rubio attacks EPA and pledges to reverse key Obama climate moves

• Republican presidential hopeful calls for increased state authority over energy
• Florida senator says EPA emissions rules would have 'devastating impact'

As Barack Obama wraps up a three-day visit to Alaska centered on the urgency of tackling climate change, Republican presidential candidate Marco Rubio on Wednesday previewed what energy policy would look like under his administration.

Rubio vowed to reverse key components of the climate agenda Obama has been touting in Alaska, while also making the case for turning back some of the nation's energy authority to the states and away from the federal government. While outlining his proposals during a swing through Oklahoma - currently the fourth largest producer of natural gas in the United States - the Florida senator decried in particular the Environmental Protection Agency's new rules to reduce greenhouse emissions under its Clean Power Plan.
