Former IRS official Lois Lerner warned her colleagues to be cautious about what they wrote in emails. Her warning came less than two weeks after an inspector general gave the IRS a draft report revealing the tax agency targeted conservative groups.
In an email to a colleague she wrote, "I was cautioning folks about email and how we have had several occasions where Congress has asked for emails and there has been an electronic search for responsive emails - so we need to be cautious about what we say in emails."
Lerner, who was the former head of the tax-exempt department, also asked if the internal instant messages were recorded.
An IRS technology official responded that instant messages would have to be manually saved in order to be found in a search, but that staffers should assume that the chats would be saved.
"Perfect," Lerner responded.
Republicans said those emails are raising even more questions about Lerner's treatment of conservative groups.
