I reached two possible conclusions for what does it mean for Mueller having access to these transition emails.
1. Nothing in the emails prove collusion between Russia and the Trump campaign.
2. Mueller knew he obtained the emails improperly and they can't be used as evidence anyway. I think number 1 is the most likely.
Axios reports officials of President Trump's transition team plan to ask Special Counsel Robert Mueller to return "many tens of thousands" of transition emails they contend were unlawfully provided to him. But the prosecutor's office says emails being used in the investigation were properly obtained.What's new: A source close to Trump's transition, which still exists as a legal entity so it can shut down what was once a 1,000-person operation, said the transition will send a letter to Mueller informing him that some of the emails are privileged, and asking for their return. The transition says it is willing to provide Mueller with vetted emails.The source told me: "What they did is totally illegal, and they need to fix it." But Peter Carr, spokesman for the Special Counsel's Office, told Axios early this morning: "When we have obtained emails in the course of our ongoing criminal investigation, we have secured either the account owner's consent or appropriate criminal process."Be smart: Republicans, who have been raising increasing questions about Mueller's office, are prepared to argue that if emails were obtained by questionable means, that could taint or undermine the investigation.
