Re: A point to ponder
If the testimony of ***** were to be considered as generally invalid there would be few successful prosecutions.
In Lev's case, he's only an accused criminal- accused of channeling Russian cash to Republicans.
Similar to Cohen I guess (although he pled guilty)- "his testimony is invalid because he pled guilty to arranging felony payoffs for Our Daddy."
Although....I have little sympathy for Cohen- I think he pulled his punches on things that he could plausibly deny.
