Former Energy Secretary Bill Richardson was elected late last week to serve on the board of trustees of the Natural Resources Defense Council. Karen Golembeski, Richardson’s spokesperson, said he was drawn to the group “primarily for its work on global climate change.” Some folks in the know expect Richardson to run for governor of New Mexico next year. Richardson served in the House and as the U.S.’s ambassador to the U.N. before becoming Energy secretary under former President Clinton. Since January, he has also joined the boards of two Texas-based oil companies.
