During the trial, Prosecutor Susan Hoffinger questioned Robert Costello about his alleged attempt to use a backchannel to Trump through Michael Cohen. Costello denied the accusation when asked by Hoffinger.
However, Hoffinger presented an email sent by Costello to Cohen that mentioned a backchannel. When questioned about the email, Costello confirmed it was his but stated that there were circumstances surrounding it that he would like to explain.
Hoffinger pressed Costello by suggesting that the email spoke for itself, to which Costello disagreed, expressing his willingness to provide further context. Hoffinger decided to move on to the next topic without delving deeper into the email.
