I am distantly related to somebody in the Secret Service. She had no military or law enforcement experience prior.
Her father was modestly high up in the military in an administrative role in DC. Then he retired to start a private consultancy where he made stupid amounts of money in a very short period on government contracts.
One day he abruptly retired from that job too. Shortly after, he and everybody else involved with his consulting business were indicted on federal bribery charges.
About a year later and after god knows how many hundreds of thousands in legal fees, the charges were dropped without explanation. A few months after that his daughter was hired by the SS.
I see these people very rarely so I don’t know their current allegiances, but they were very pro-Trump during the first couple years of his administration.
