well, among the u.s. officials who were at that meeting, in addition to those people i just pointed out, was this person in the second row here. that's an aide to mike pence, someone detailed to the pence office. she's named jennifer williams. she was also listening in on the july 25th phone call between president trump and president zelensky. the one where zelensky asked trump for military aid and trump said said do us a favor, though. jennifer williams, that official appeared on capitol hill today to give testimony on the impeachment proceedings, she's the first person from the president's office to do so. but i want to point out one other thing, also at that september 1st meeting was the man we spot shadowed here. this was the senior director on the national security council who was involved in ukrainian negotiations. today while jennifer williams was testifying behind closed doors in the impeachment proceedings that other guy who was also there at that meeting quit his job.
