“My emails, the Blackberry I carry around, all those records are available and archived,” Mr. Obama said, according to an excerpt from the interview released Saturday evening. “I’m glad that Hillary’s instructed that those emails about official business need to be disclosed.”

In the portion of the interview that was released, Mr. Obama did not address how he could have avoided noticing that Mrs. Clinton was sending emails from a “clintonemail.com” address throughout the years she served in his administration. Mrs. Clinton’s use of a private email system was first reported by The New York Times last week.

Asked how Mrs. Clinton’s email practices met the standards of transparency that he has repeatedly called for, Mr. Obama said that “the fact that she is going to be putting them forward will allow us to make sure that people have the information they need.”
