Politico has the story:
Energy Secretary Steven Chu is stepping down, ending a four-year tenure marked by milestones in green-energy spending along with withering attacks from Republicans and the collapse of the solar company Solyndra.
Chu announced Friday that he intends to resign once a successor is confirmed, according to a memo sent to Energy Department staff and obtained by POLITICO. He was the last of President Barack Obama’s long-serving Cabinet members to announce plans to leave or stay for the second term.
Read the rest at the link. We’ll certainly have more about this later. For the moment, a tidbit: Chu will be the longest serving energy secretary since the founding of the department.
