It is NEVER allowable for anyone to be in a house, in a condo, in an apartment with FBI agents as they go through a search. They must stand outside and wait until it is done.Don't Trump's lawyers know what was listed in the warrants?
My understanding is although the agents said the security cameras must be turned off, they were also left on., so any kind of shennanigans that trump tries to pull about "planting things" like an OJ gloves theory, will be provable that its a another lie.
He wasn't treated nor was his lawyers nor was his house any differently then anyone else any other citizens in the United States with a Search Warrant.
Why should he?
