The lawyer of the man suing to have the American election overturned is not a reliable source of factual information. That's like believing Charles Manson's lawyer when he says his client is innocent.
Get a third-party confirmation on anything Sidney Powell does not say under oath. Even in the quote from her, we can see she is not the primary source on this information. "But I do not know if good guys got it or bad guys got it." She's relaying information she's received second-hand, and since her client is known to believe unsubstantiated conspiracy theory, it's safe to assume a modest probability that the second-hand source is unsubstantiated conspiracy theory.
(Also, as a useful first-pass filter on baloney, any news story that starts with a blast-word like "HUGE!" is probably not going to pass the sniff test for veracity. Rags use blast-words because they have to make up for their lack of integrity with spectacle. News organizations with a reputation to lose just use short-sentence headlines).
a) Trump is a primary source of what Trump said; there's no fact checking involved. You either take Trump as a reliable source of info about himself, or you don't. If you don't, this entire conversation is moot because you're claiming a guy who can't even tell who his legal team is is playing 4D chess. If you're trusting some "my mother's cousin's sister works at the Pentagon and she heard what's really going on is" source over the words of the plaintiff in these cases, that's your problem.
b) Check the dates of the tweet vs. the headline. She was on his legal team; now she's not. Kicked off. Incompetent hiring isn't 4D chess.
Honestly, this is the problem with QAnon. If the only way to conclude the dumbest guy in the room is actually the smartest guy in the room is to assume he's the smartest guy in the room and to work backwards to figure out how that might possibly be true, Occam's Razor suggests we already have our answer.

At this point, the best reason I can propose that the CIA wasn't invited to the overseas raid is there wasn't an overseas raid.
This is Comet Ping Pong all over again and I'm watching you fall for it in realtime. It's sad. :(
