It’s not out of order for Tucker or any reporter to ask for evidence or something to support her claims.
If she did not wish to describe any such evidence, she should not be popping up on these kinds of programs.
Just issue a Press Release and take no questions if this is to be a one way dialog at this present time.
What is a Host supposed to do, just accept whatever someone claims as fact with little to back it up? We get after the CNN’s of the media for doing the same thing.
Sounds like a rational approach to me
