President Trump Trump is like most executives. When they are with people they should be able to trust, they throw out thoughts (bounce against a wall). We know he hates corruption and wants it stopped.
Darn auto complete
Not only does a chief executive throw out thoughts to trusted advisors, he tailors the thoughts to the expertise of the advisor at the time. Those advisors don't know what other thoughts were expressed to other advisors.
So, if an advisor like Bolton puts in a book that President Trump wanted to tie aid to an investigation, he only knows the thoughts that were expressed to him. He wouldn't know if Trump asked someone else what if we don't tie aid to anything?
