Yep. Interesting choice of pseudonyms too. In Tom Clancys novels Peter Henderson is a KGB mole that infiltrated US government.
It is unclear whether this change was on Hunters end (on his devices) or on Joes, but Peter Hendersons e-mails included messages such as Keep in touch, Love Dad and shared links often about Hillary Clinton
