In 2012 it was revealed that Obama administration officials used pseudonym email accounts to hide their communications.  EPA head Lisa Jackson became embroiled in a scandal when it was discovered that she subverted FOIA concerns by using an account under the name “Richard Windsor”, a name attributed to her dog.
Later, as the EPA scandal evolved, Lisa Jackson quit her position. 

Now, it appears that IRS official Lois Lerner was doing the exact same thing.  Using the email name “Toby Miles” to hide her in house, and ex parte, communication.  The IRS plot thickens.
WASHINGTON DC – The IRS admitted to a federal court there was a second personal email account that Lois Lerner, the official at the heart of the Tea Party targeting scandal, used to conduct agency business.
The email account apparently was set up under the name, “Toby Miles,” which sources tell Fox News is the name of Lerner’s dog.  
The admission, first reported by The Washington Times, was made Monday in an open-records lawsuit filed by Judicial Watch, a conservative group suing to see Lerner’s emails sent during the targeting of conservative groups filing for tax-exempt status.
IRS lawyer Geoffrey Klimas told the court that as it was putting together a set of documents to hand over to Judicial Watch, attorneys discovered another email account, in addition to her official account and a separate personal email already known to the agency.
“In the process of preparing this status report and for the August 24, 2015, release of Lerner communications, the undersigned attorneys learned that, in addition to emails to or from an email account denominated ‘Lois G. Lerner‘ or ‘Lois Home,’ some emails responsive to Judicial Watch’s request may have been sent to or received from a personal email account denominated ‘Toby Miles,’” Klimas told U.S. District Judge Emmet Sullivan.

Unfortunately for ordinary Americans, neither the Democrats nor the Republicans -who benefit from the IRS targeting of conservatives- will be in any hurry to expose this corruption within DC.
