Yes, and this is a major, major problem at all levels of federal government. It's quite stupid to limit your talent pool to specific universities, or to universities at all. It selects for elitism, mediocrity, and groupthink.
Agencies like the FBI and CIA should be recruiting, to a large extent, from law enforcement, not from universities.
Further, I don't think these agencies can be trusted to police themselves, ever. There has to be much, much better oversight - and a non-government/civilian component of this oversight. The penalties for abusing power from within an intelligence agency should be similar to the penalties for being a spy. Both are cases of subversion.
The culture of Leftism is far too deeply embedded to fix.
Commies have been exclusively hiring and promoting commies for decades now.
Brennan voted for a Stalinist in 1976, when the Soviet Gulags were full, admitted it on his CIA intake polygraph, and he rose to become director of the CIA.
And it’s only gotten “progressively” worse since then.
They recruit from DOD too. Where else can you get a 007, Matt Helm, or someone to get heir hands bloody.
