President-elect Barack Obama has nominated Shaun Donovan to head the Department of Housing and Urban Development. Donovan is currently the head of New York City’s Department of Housing Preservation and Development. Meanwhile, Chicago School Superintendent Arne Duncan has emerged as Obama’s choice to become Secretary of Education. And Colorado Senator Ken Salazar is expected to be named Secretary of the Interior. The selection of Salazar has disappointed many environmental groups. A coalition of 141 environmental groups, biologists and other scientists had launched a campaign for Obama to pick Arizona Congressman Raul Grijalva for the post.
