WASHINGTON — Energy Secretary Steven Chu, who won a Nobel Prize in physics but came under questioning for his handling of a solar energyloan, is stepping down.
Chu offered his resignation to President Barack Obama in a letter Friday. He said he will stay on at least until the end of February and may stay until a successor is confirmed.
Chu’s departure had been widely expected and follows announcements by Interior Secretary Ken Salazar, Environmental Protection Agency chief Lisa Jackson and Jane Lubchenco, head of the National Oceanic and Atmospheric Administration, that they are leaving.
The White House said no decisions have been made on replacements for any of the environment and energy jobs but said Obama’s priorities will remain unchanged. Potential replacements for Chu include former North Dakota Sen. Byron Dorgan, former Michigan Gov. Jennifer Granholm and former Washington Gov. Christine Gregoire.
