That was criminal slander, not to mention an illegal attempt to interfere with the legally required investigation.
The fact that to this day, the firing of Shokin, Burisma Holdings, Hunter's millions, the laptop, etc. have never been fully investigated, is a horrendous crime.
And in fact, all those accusing Trump of crimes, like Russian collusion, Ukraine intimidation, classified doc violations, sexual assault, etc., clearly have no legal basis and instead are all guilty of bearing false witness in criminal charges.
Trump is sleazy, but never committed a single crime that has any proof at all.
