obviously an after the fact CYA move by Rice to protect herself because she knew that they were breaking the law. She also knew that BHO would not take kindly to being named in it and having his involvement in taking down Flynn and illegally spying on Trump & his people, so she put in the term "by the book" twice, and tried to make BHO look like the stand up angel that he isn't.
By Rice's own email, Comey told Obama that they did not have any evidence that Flynn was doing anything wrong. She further claims that Comey said, "but the level of activity is unusual". What level of activity exactly is "unusual" for an incoming National Security Advisor to have with a person in the same position from another Super Power? The BEST case argument that you have is that Obama chose to spy on Trump and take down Flynn because Comey thought "Well, we don't see anything wrong, but he does seem to talk to them a lot".
Utter bullshit. The Obama administration is the most corrupt administration ever. They even blocked important sensitive info from the incoming tea,.. Obama obstructed the peaceful transition of power, and attempted to carry out a silent coup with planted loyalists who leaked to a complicit liberal media on a daily basis.
