Obama administration officials say they want Congress to pass an emissions-cutting law but are prepared to proceed with EPA rules if Congress does not act.
Murkowski is vice-chair of the Senate Republican Conference and is also the ranking member of the Senate Energy and Natural Resources Committee.
