Obligatory Politics Warning.
Quick note to the IRS: Email doesn't work that way. How it works is more ably explained in links at the link, but, if my computer crashes, I don't lose my emails. You know how you can access your GMail from your work computer AND your home computer?
Yeah. That's more how email works.
This excuse? I'm embarrassed for the people who had to make it. But, empathy only goes so far. The IRS deserves to be better managed and not have what little public faith remains in it shattered to protect political actors. We need to investigate it, now. If it turns out the IRS's email architecture is so archaic that this IS how their email works, well then, at least we can fix that.
