Chicago: U.S. President-elect Barack Obama shifts his focus to the second half of his White House Cabinet next week with decisions pending in the high-profile areas of energy, the environment, trade and agriculture.

Obama, who takes over for President George W. Bush on Jan. 20, has already put his economic and national security team in place, but has made it clear that other areas -- especially climate change policy -- will be priorities too.

Officials within his transition team have kept quiet about a handful of names making the rounds for each of those posts.

Obama will hold a news conference on Sunday, the anniversary of Japan's 1941 attack on Pearl Harbor that brought the United States into World War Two, to discuss "the contributions of those that have served our nation," his office said in a statement.

He is also to appear on a Sunday television news program where he may be asked about plans for further appointments.

One important supporter during Obama's campaign, Kansas Gov. Kathleen Sebelius, is a top contender for an administration post, possibly as energy or agriculture secretary.

"Governor Sebelius is honored to be mentioned as a potential secretary and will do whatever she can to help the Obama administration," her spokeswoman said in an e-mail, declining to comment on "hypothetical" jobs.

The popular Democratic governor, who was on Obama's short list of potential vice presidential picks earlier this year, has made a big push for renewable energy in Kansas, setting a target for 20 percent of the state's energy needs to be met with wind by 2020.
