They're two separate issues. The divulging of classified information is a crime, using personal email upon which to conduct public business is not a crime. You're not supposed to do it, it's not best practices, it actually violates status and regulations. So you should keep the record. Miss Clinton should do it, Eric Holder, right?
Everyone throughout government who conducts official business should use official email. I've never called for Hillary Clinton to be prosecuted, and I couldn't possibly have done it for using private email, because it's not a crime. I've already talked to Miss Trump's attorney, I've already talked to Mr. Cummings, we've already written a letter to the White House.
Congress has a responsibility to make sure that the records and the Presidential Records Act is complied with. And that is true no matter who the person is, whether it's Secretary Clinton or whether it's Tom Perez or whether it's Ivanka Trump.
