The Obama administration is not willing to trade drilling in the Alaska National Wildlife Refuge for an agreement to establish a new fund to research cleaner automotive technology, one of the president's advisers said Tuesday.

Heather Zichal, deputy assistant to the president on energy and climate change, told reporters at the National Press Club that while the administration is committed to launching the Energy Security Trust Fund, it is also determined to keeping the iconic refuge off-limits to oil and gas exploration. Obama campaigned for the trust fund on Friday at the Energy Department's Argonne National Laboratory, saying that spending $2 billion in federal royalties from offshore oil and gas drilling on research into clean energy over the next decade could shift the nation's cars and trucks off oil.

"ANWR's off the table," Zichal said.
