With the news today that one of the U.S.'s largest utilities, Exelon, is dropping its membership to the U.S. Chamber of Commerce, I thought our readers would be interested in a story that ran on National Public Radio this morning regarding the association's CEO Thomas Donohue.

The story said environmentalists and others are concerned about whether Donohue can be an unbiased leader on the climate change debate because he sits on the board of Union Pacific, which has a stake in the outcome of the debate.

Exelon CEO John Rowe said he won't renew membership in the business group because of its opposition to climate change legislation. Exelon follows utility company PG&E, which announced it was pulling out of the U.S. Chamber last week because of the group's opposition to similiar legislation.
