Below is lifted from a CNN website article on the time line. Note that the scandal erupted in May of 2013.
“How do we know Lerner’s hard drive really did crash?
The IRS has supplied CNN and others with emails between Lerner and the IT department during the time of the crash.
At the end of a chain of emails, on August 5, 2011, an employee wrote, “Unfortunately the news is not good. The sectors on the hard drive were bad which made your data unrecoverable.”
Lerner replied, “I really do appreciate the effort. Sometimes stuff just happens.”
