In an email exchange released Sunday by WikiLeaks, Hillary Clinton's campaign chairman John Podesta implied her lawyer and long-time friend Cheryl Mills came up with the idea of Clinton using a private email server while secretary of state.

When campaign advisor Neera Tanden asked, "Do we actually know who told Hillary she could use a private email? And has that person been drawn and quartered?" Podesta responded, "Don't you think Cheryl?"

Mills was questioned by the FBI in connection to the email investigation and, in an unusual step, was allowed to be present during Clinton's interview as her counsel.

To Podesta's suggestion it was Mills, Tanden responded, "I repeat, why hasn't this person been drawn and quartered? I'm reading wolf hall. There is something to be said for the power of torture."

The Daily Caller previously reported Tanden's response, but the most recent WikiLeaks release shows Podesta's subsequent response.

"At least we now know why Cheryl didn't want her to run," Podesta responded.
