No Kellyanne has no way of letting Trump know someone wants to interview him because she follows protocol, it's not like she just could walk in on Trump having a telephone conversation.The audio of Woodward-Trump tells you all you need to know: skip the book.
Trump is effectively a puppet president who only gets the intel that his handlers think he can manage without doing something totally stupid. And the way Kellyanne talks, it seems that it is Kelly who decides what the president gets told and who he gets to see.
Trumpsters must be so proud.
