This CYA email that Rice sent to herself 15 days after the Jan 5, 2017, meeting in the White House is another attempt by this devious woman to save her master, Obama, from his failed plot to defeat President Trump and install Hillary as president AFTER the election. Subpoena everyone who was at that meeting.
Without reading the entire email, I can only speculate. It was a CYA for the group and especially for Rice and BHO. The “do it by the book” was window dressing, to make it look like BHO wanted to make sure he was on record of following the law. The “if there is any reason that we cannot share information fully as it relates to Russia” is there to support the (conspiracy) investigation that Trump was colluding with Russia to fix the elections and why BHO did all the things he did to “save America”.
It would be interesting to search Rice’s emails to see how many times in her tenure that she posted emails to herself and the contents of those emails. A very different light shall be cast if this was the only one.
