if you were cynical, you might say this is just yet another attempt at spin; to present himself as a relatable human (like "we all get angry, we all make mistakes", although note he didn't use e.g. angry, but "frustrated", "upset", and "emotions", vaguer and more passive options).
this could work, too, as long as you forget that drafting words seems to literally be his job (for which i'm sure he's handsomely rewarded).
