Williams and Kalvin are YouTubers who supported Trump during the election. Their Facebook page was shut down once it it was known to be a Russian backed propaganda account.

'Efforts to reach out to Facebook friends of Williams and Kalvin, who also joined their sole Facebook group, “#BlackLivesMatter against #PoliceBrutality,” also did not receive a response. None of Williams or Kalvin’s Facebook friends are from Atlanta, where the two claim they live on Facebook and in videos. On Facebook, both Williams and Kalvin claim their hometown is Owerri in Nigeria.
In 2015, Williams Johnson claimed he had just spent his “first Thanksgiving with my LIL BROTHER in America!” and attached a since deleted Tweet from Alex Jay, who is a rapper and Instagram model. Jay told The Daily Beast he had never heard of Williams.'
