Which report was a smear?
We saw this a lot in the Russia hoax. Specifics are left out because the allegations in those reports are true, not smears.
For instance...
There's a letter from George Kent, Mr. Bowtie, confirming they did.
Did she not violate Geneva and piss off Ukrainians calling for the firing of an anti-corruption special prosecutor?
That leaves Yuriy Lutsenko (prosecutor) alleging Yovanovitch had a "do not prosecute list" for him in their first meeting in 2016.
We hear he recanted. But The New York Times reported he did not.
Why wasn't he invited to testify to find out under oath?
Again...
They're not factually inaccurate "smears" but rather unflattering accounts of her behavior while serving in her former role.
