The Environmental Protection Agency is the latest Obama bureaucracy exposed for embarrassing efforts to avert transparency. Its administrator, Lisa Jackson, has been using the email alias “Richard Windsor” to conduct agency business, which might allow some policy conversations to avoid scrutiny and circumvent public records laws.

So far, the EPA has offered a two-part defense of such accounts, first revealed in my new book, “The Liberal War on Transparency.” First, everybody does it: “For more than a decade, EPA administrators have been assigned two official, government-issued email accounts: a public account and an internal account.” Second, the masses made us do it: the overwhelming volume of mail an administrator would receive from the public meant she needed an account she would actually read and write from.
