Top Obama administration Obamacare official told staff to delete email

Isn't this a felony?

In a letter to Centers for Medicare and Medicaid Administrator Marilyn Tavenner, the Republicans point to an Oct. 5 email from Tavenner to staff about how to handle calls from people applying for ObamaCare.
In the first line of the email, Tavenner writes “please delete this email but see if we can work on call script.”
Republicans in their letter ask why Tavenner wanted the email deleted, and whether she has asked for other emails to be deleted.
“This contradicts … [the claim] that your practice was to instruct subordinates to retain copies of e-mails,” said the lawmakers, including House Energy and Commerce Committee Chairman Fred Upton (R-Mich.) and Oversight Subcommittee Chairman Tim Murphy (R-Pa.).
