Yeah, that’s going to be absolutely necessary everywhere. It will need to be performed multiple times, by multiple independent agencies, and double-checked. And intelligence personnel hired during the Trump administration will need to be vetted heavily.
They will have to clean house. Every person in the white house that was hired by Trump and his administration will have to be removed from the gardeners and cooks to any administrative assistants. I have a feeling there will be a lot of indictments coming when its all said and done.
