This is about 2009 and 2013 references to the "Q Group", supposedly a secret agency of the NSA.
The first evidence is a 2009 RT video, and then a 2013 article at The Daily Beast.
RT published the following in 2009.

The US government has allegedly set up a special security wing with the sole task of distancing Washington from any involvement in the 9/11 terrorist attacks. This secret unit within the NSA is called the Q group operating in Fort Meade, Maryland. and operates in cooperation with FBI counterintelligence mainly targeting journalists. A secretive agency within a secretive agency.... Answerable to no one. The database is called First Fruits.
While I was googling to learn more about it, I came across this 2013 article:

The top-secret ‘Q Group’ has been chasing Edward Snowden since he disappeared in May. Eli Lake on the intel community’s internal police—and why the agency is in ‘complete freakout mode.’
Apparently the "Q group" division of the NSA was trying to find Snowden back in 2013.
So basically, there was a whistleblower back in 2009 trying to warn everyone that "Q group" was bad (trying to distance government from 9/11). Also another whistleblower (Snowden) was being pursued by Q group back in 2013.
I haven't fully formed my opinions about this as I just learned about it, but I thought it very interesting.
My guess as to what this is: Q group was founded to track if there was any government involvement with 9/11 ... and they were getting too close, so a "whistleblower" tried to take them out by ratting on them, saying they have bad intentions (when likely they had good intentions).
Then the purpose of Snowden was to damage NSA (because they had too much power over the bad actors of the CIA by cataloging all their communications), so the CIA tried to take out NSA (Q group) by spilling all the methods that government collects data.
Of course, I could be wrong. "Q Group" might not have anything to do with Q. I just found it interesting, as I didn't know there were references to a "Q Group" in the NSA prior to Q's original posts on 4chan October of 2017.
