with this e-mail string, mr. cohn could have forwarded this e-mail directly to mr. davidson and would not have had to take the interim step of going to his personal e-mail account. what we believe happened and this is speculation, but good speculation is that he sent it from his personal e-mail address, he forgot to delete the middle portion of the e-mail that showed the communication had been taken place with his e-mail at the trump organization. >> michael cohn has gone on defensive today. >> i often use personal e-mails for personal business. i don't think that is unusual.
