Sen. Barbara Boxer (D-Calif.), who heads the Environment and Public Works Committee, insisted Tuesday that her panel will introduce sweeping energy reform legislation by the end of the month.

"The bill will be introduced this month, and we're going to be marking it up shortly thereafter," Boxer said.

The Californian, who has been working alongside Foreign Relations Chairman John Kerry (D-Mass.) on the bill, tossed aside suggestions that the Senate's overwhelming focus on health care reform will curtail its ability to also tackle energy policy this year.

Six Senate committees have jurisdiction over climate change: Agriculture, Nutrition and Forestry; Commerce, Science and Transportation; Energy and Natural Resources; Environment and Public Works; Finance; and Foreign Affairs. Boxer maintained Tuesday that jurisdictional issues over which committee is responsible for certain portions of the energy bill will not be an issue.

"I think all the committees will do their work. We'll do our bill, the others will do their bill and the [Majority] Leader will marry it," she said.
