It appears that the ex-spokestranny never returned to Ukraine after the washington trip. As of yesterday, he is in Panama now investigating "migration issues" and apparently how everything on the US southern border is Russia's fault. He will be continuing his investigation all over central and south America supposedly.

He also did an explicit tweet about a week ago where he denied being a military spokesman for Ukraine. That was somewhat odd and something he had never done before than I can remember.

His twitter status also says that he is "on leave" from the AFU. Its sure looking like they brought him back to the US and dumped him on the sidewalk.
