Suspect amicable separation. Powell is not a paid member of the team. She is working on a separate track, i.e., massive computer voter fraud. Her efforts are overshadowing Rudy’s efforts and could hurt upcoming court cases.
Also, Powell is going after Kemp, CIA, FBI, etc. GOP worried about impact on Jan 5 runoff. That said, Powell’s efforts is the hill Trump should die on. Much bigger numbers involved to overturn election results. Powell will go forward with legal case, probably file on Wednesday. Release the Kraken.
Who though does Powell represent, if not Trump? A set of Georgia voters, perhaps.
