State of Play: Fresh layoffs in the coal and wind industries are fueling congressional battles over energy policy ahead of the elections.

Republicans are seizing on job losses at coal mining giant Alpha Natural Resources as they seek support for legislation to kill, soften or delay various federal rules that affect the coal industry.

The House will vote later this week on the bill, which would upend federal greenhouse gas regulations and other White House policies that Republicans allege are harming the coal industry.

The House Rules Committee is slated to meet Wednesday afternoon to vet amendments that could receive floor votes when the bill comes up. A final floor vote on the bill is expected Friday.
