All three email aliases, including the one Holder currently uses, are official Justice Department addresses on the @usdoj.gov domain, the official told The Huffington Post. Holder has used the aliases to prevent spam and to keep his inbox from being overwhelmed by the public, not to avoid transparency, the official said. The addresses were known to DOJ officials handling Freedom of Information Act requests and congressional inquiries, according to the official.

“The Attorney General uses a Justice Department email address to conduct official business. As with many Cabinet officials, he does not use his given name in the handle of his email address,” Justice Department spokesman Brian Fallon said in a statement. “This practice is similar to using initials or numbers in an email address and helps guard against security risks and prevent his inbox from being needlessly inundated. It does not in any way impact compliance with FOIA requests. The Attorney General’s email address is known to the individuals who process FOIA requests, and his emails are regularly produced, albeit with his exact address redacted.”
