The new head of the Environmental Protection Agency is getting down to work.
Lisa Jackson was confirmed on Friday after Wyoming Sen. John Barrasso held up the confirmation over questions regarding how Jackson would interact with new White House energy czar Carol Browner.
The 46-year-old Jackson is the first African-American to lead the EPA. She previously led New Jersey's DEP.
In an open letter to EPA employees on Friday, she promised to bring scientific thinking to the EPA and to make the agency "follow the rule of law."
She said her primary goals would be to reduce greenhouse gas emissions, improve air quality, deal with the risks posed by chemicals, clean up hazardous-waste sites and protect bodies of water from pollution.
