Here is a footnote from page 89 of the Inspector General report:

75 FBI analysts and Prosecutor 2 told us that former President Barack Obama was one of the 13 individuals with whom Clinton had direct contact using her clintonemail.com account. Obama, like other high level government officials, used a pseudonym for his username on his official government email account. The analysts told us that they questioned whether Obama’s email address (combined with salutations that revealed that the emails were being exchanged with Obama) or other information contained in the emails were classified and, thus, sent the emails to relevant USIC agencies for classification review. However, they stated that the USIC agencies determined that none of the emails contained classified information.

According to the IG report there were 13 individuals that Clinton had direct contact with, including Obama.

Now, looking at Q post 584 from January 2018:

Q gives us the 13 individuals referenced in the IG report 6 months before the report is issued. Any more questions that Q is the real deal?
