The Senate could vote Thursday to confirm the nominations of two of the administration’s top scientists.

John Holdren, nominated as President Obama’s science adviser, and Jane Lubchenco, nominated as administrator of the National Oceanic and Atmospheric Administration, appeared before the Senate Commerce, Science and Transportation Committee to a warm reception.

The panel approved both nominations by voice vote.

John D. Rockefeller IV , D-W.Va., Commerce chairman, said he and ranking Republican Kay Bailey Hutchison of Texas are seeking to have the nominations confirmed on the Senate floor by voice vote as soon as possible.

“Speed is important here,” Rockefeller said.
