From U.S. News:
…just a week after E-mails in the U.S. attorneys case became a main focus of congressional Democrats probing the firings, several aides said that they stopped using the White House system except for purely professional correspondence.
“We just got a bit lazy,” said one aide. “We knew E-mails could be subpoenaed. We saw that with the Clintons but I don’t think anybody saw that we were doing anything wrong.”
