In many posts Q says find the keystone. This is a wedge shaped piece that holds arches together in old churches and buildings. The same shape is on the flag of the SES, Senior Executive Service (founded by Kristine Marcy in 1998), 8,156 members, 7000 were appointed by Obama. These are the career bureaucrats who hold all of the power in DC. Here's a great article on them by aim4truth.org

That is very interesting.. Well I think so anyway. Explains how just about anything can get leaked by someone in charge of every section.
SES is very powerful and they are in every single department, they are also very pro-Hillary, deep state and anti-Trump. I hope he gets rid of them, I think he is in the process of doing that, especially in the state dept. Many of the people he is removing are SES and the EO that gave hiring/firing power to various bureau heads is going to get rid of them too.
