“President Trump is capable of contacting her if he so chooses.”
Yes; she knows that. That’s probably why she went public with her statement — to get the word out to him that his handlers have put a firewall around him. He may appreciate that information and can contact her.
As I posted on another thread, President Trump tweets.
That means he also readssocial media and will find out that Powell has been blocked.
He may not know it yet. He has a workload that will not allow him the time to read every post on the internet, but eventually.....and woe to those who sabotaged his efforts.
