President-elect Barack Obama is now focusing on filling the remaining positions in his White House Cabinet, particularly in the areas of energy, the environment, trade, and agriculture. While he has already assembled his economic and national security team, Obama has emphasized that issues such as climate change policy will also be top priorities. The names of potential candidates for these positions have not been disclosed by his transition team. Obama will address the media on Sunday, which marks the anniversary of the attack on Pearl Harbor, to acknowledge the contributions of those who have served the nation. He is also expected to discuss any future appointments during a television news program appearance. During Obama's campaign, Kansas Gov. Kathleen Sebelius was a significant supporter and is now being considered for a cabinet position, possibly in energy or agriculture. Her spokeswoman stated that Gov. Sebelius is honored to be considered and will support the Obama administration in any way possible, but declined to comment on specific job possibilities. Sebelius, a popular Democratic governor, has been a strong advocate for renewable energy in Kansas, aiming for 20 percent of the state's energy to come from wind by 2020. Obama has also pledged to increase the use of renewable energy in the U.S. to reduce reliance on foreign oil suppliers. Industry insiders mentioned that Dan Reicher, climate director at Google.org and a former Energy Department official during President Bill Clinton's administration, was a strong candidate for energy secretary. In an interview with Reuters, Reicher did not comment on his potential appointment but expressed his enjoyment of being on Obama's transition team. Another source suggested that John Podesta, Clinton's former White House chief of staff and current co-chair of Obama's transition team, could also be considered for the energy secretary role or the newly created position of climate "czar." Carol Browner, who served as administrator of the Environmental Protection Agency under Clinton and currently leads Obama's energy and environment task force, is also a top contender for the climate chief position. A decision on these appointments is expected in the coming weeks, though vetting for the positions is not yet complete. Obama officials are still determining how a climate official in the White House would impact the roles of other policy players. Lisa Jackson and Mary Nichols are being considered for the position of EPA administrator. Obama met with Xavier Becerra to discuss the role of chief trade negotiator, potentially making him the first Hispanic to hold the job. John Salazar, Sanford Bishop, and Kathleen Sebelius are top candidates for agriculture secretary. Joe Biden has chosen Jared Bernstein as his chief economist and economic policy adviser. Bernstein was the deputy chief economist for the Department of Labor from 1995 to 1996.
