I would suspect that they are professional liars. Just watching a snippet of the people interviewed indicated to me that they were lying. All you had to do was watch their eyes and facial expressions to know they were lying.
I’m sure we aren’t hearing the whole story. It will probably fall apart if we public testimony. But so what if what this guy heard is true? We know the day before Trump asked him to investigate. So asking about it the next day is not surprising. Just dems and MSM salivating again as usual.
