They say x, ask for where they heard about x. They say from y news organization, ask the source for y. If they say z, if z is actually an actual document or otherwise, ask them where in z does y claim x is true.
If z is just another news organization, keep going until they provide (or don't provide) an actual document. If they can't procure an actual document, send it yourself. If z is just another video cIip, ask them for the whole video. Provide them the entire video if they can't.

He's been on radio and TV for over a quarter century. I onlt want 1 example to prove your statement.
Nothing.
So I say, "So you are one of those people. Who will destroy a good mans name, bare false witness because someone on TV who you've never met says so."
To this day they never speak of politics in my presence. Make no mistake, this is noticed.
