(CNN) An impersonator posing as a Bernie Sanders campaign official contacted at least two other Democratic presidential campaigns in an attempt to arrange calls with their candidates.

CNN on Friday obtained an email sent from a suspicious address to another Democratic campaign. The impersonator reached out to the campaign from a web address that was designed to look like it was part of the Sanders campaign, posing as scheduler and seeking to arrange a phone call between Sanders and the other candidate.

"The Senator would like to discuss a few controversial issues relating to our primary campaign and to explain his position on some of these topics to clear up any misunderstandings we have. For example, about foreign dictators," the email read.

"And also the Senator would like to explain his vision for the ongoing primary campaign."

The email concludes with a request for "any additional details you think we should be aware of for our planning purposes." An email from the same domain address was sent to at least one other campaign, a source told CNN on Friday.
