The ambassador has already been shown via a FOIA to have lied during the impeachment hearing.
She said quite clearly that the only time she heard about Burisma was when she was briefed at foggy bottom for her confirmation hearing.
There are numerous emails that specifically mention Burisma as well as some meetings that she seems to have forgotten.....
I just wasn’t sure if just referencing the ambassador was specific enough, Is there anyone else in that category?
