If you did your homework, you would have read at least two articles which stated that the Kenyan government said that no Obama relatives were allowed to speak to journalists or others without getting government permission. It was before inaguration.
Maybe even three articles. I read each and every thread I can find about this topic. It takes time and effort to find things out.
If you want to know stuff, you have to do the same. Plaques about his birth place are not the same thing as relatives being forbidden to talk to any foreigners unless getting permission from the government, which is what happened.
Um, I did do research and found multiple articles about Obama’s grandmother holding court in front of her house in Kenya on January 18, and about other family members’ preparations to attend the inauguration. Holding what is basically a press conference to talk about your grandson becoming president of the US isn’t what I would interpret as being shut down by the government.
