Rubio announced the expulsion on his way back to Washington from a G7 foreign ministers meeting in [Canada](https://www.newsbytesapp.com/news/world/canada).
Neither Rubio nor the State Department immediately responded to why he had decided so.
However, Rubio posted a _Breitbart_ article on Rasool's comments on the webinar hosted by a South African think tank earlier in the day.
Rasool's talk addressed Trump's administration's policies on diversity, equity, and immigration, and he discussed these in the context of demographic changes in America.
