President-elect Barack Obama will be focusing on filling the remaining positions in his White House Cabinet next week, with key decisions to be made in areas such as energy, the environment, trade, and agriculture. While he has already assembled his economic and national security teams, Obama has emphasized that issues like climate change policy will also be top priorities. Names for the vacant posts have been circulating, but his transition team has not confirmed any appointments. In addition, Obama will hold a news conference on Sunday to honor those who have served the nation, coinciding with the anniversary of the attack on Pearl Harbor. He is also scheduled to appear on a television news program where he may discuss his future appointments. During Obama's campaign, Kansas Governor Kathleen Sebelius was a key supporter and is now being considered for a position in the administration, potentially as energy or agriculture secretary. Her spokesperson stated that Governor Sebelius is grateful for the mention and is willing to assist the Obama administration in any way possible, but did not comment on specific job possibilities. Governor Sebelius, a popular Democrat who was previously considered for vice president, has been actively promoting 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 sources in the U.S. to lessen dependence on foreign oil suppliers. Industry sources mentioned that Dan Reicher, climate director at Google.org and a former Energy Department official in President Bill Clinton's administration, is a strong candidate for energy secretary. Reicher, speaking to Reuters on Thursday, did not comment on his chances but expressed enjoyment in being part of Obama's transition team. Another potential candidate for energy secretary or climate "czar" is John Podesta, Clinton's former White House chief of staff and current co-chair of Obama's transition team. 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 being considered for the climate chief position, according to a source familiar with the process. A decision on these positions is expected in the coming weeks, as vetting is still ongoing and Obama officials are determining how a climate official in the White House would impact other policy players. Lisa Jackson, who previously served as commissioner of the Department of Environmental Protection in New Jersey, and Mary Nichols, who was an assistant administrator for the EPA during the Clinton administration, are being considered for the position of EPA administrator. In terms of trade, President-elect Obama met with California Democratic Rep. Xavier Becerra to discuss the role of chief trade negotiator. Becerra, known for his cautious approach to international trade agreements, would be the first Hispanic to hold this position. Other top candidates for agriculture secretary include John Salazar of Colorado, Sanford Bishop of Georgia, and Kathleen Sebelius. Vice President-elect Joe Biden has appointed Jared Bernstein as his chief economist and economic policy adviser. Bernstein worked as the deputy chief economist for the Department of Labor from 1995 to 1996.
