The FBI have to be the G-Men that I grew up knowing. I used to listen to Old Time Radio every Sunday night when I was a kid as it helped me sleep, many of these were from the 30s to the 50s and they often covered FBI stories.
Then there was the 1980s in which the FBI handled Russian spies with the utmost professionalism, even as they sometimes had to let men they strongly suspected were spies but, their fidelity to their motto and principles reigned supreme.
You need that FBI. They were known around the world known as the best. I don't follow them much now or follow their stories but they do seem to be more political than in the past. Hell, they were the original purveyors of America First long before Reagan coined the term.
I don't know much about Patel or any other nominees outside of Rubio and Gabbard to a lesser degree. He must maintain that former reputation and also remain apolitical regardless.
