The former White House press aide told the Times that he has been "humbled" by the reaction from Trump supporters to his book, while noting that he still feels resistance from Washington's political establishment.

He added: "Did I make mistakes? Thank you for taking me down memory lane. Absolutely. Do I hope I grow as a person, as a friend, as a stranger to do better? Absolutely.”
