Careers and lives were heavily impacted when Bill Clinton took office in 1993 and replaced many working level FBI agents at the GS-14 level. It was shocking because those replaced were hard-working, honest, competent, experienced, and objective. I had not seen anything like that in any previous administration.
The Clintons put their own people in. Then FBI files started disappearing and showing up in the White House.
How many of that group are still there?
Enough deep state Clinton and Obama deep state types to fix any crime that needs fixing.
