I hope you are also referring to the Clinton and Obama years correct? They had some characters that IMHO would never get the badge with the dark purple stripe ( Thats what the color was in aerospace ) ..
Oh, but Clinton and Obama vetted their staffs. They were all Marxists and collaboraters, therefore found reliable. lol.
I never got the feeling Trump brought on people into the WH that he even knew all that well. Certainly, few of them were old trusted pals or even wise hands from the Beltway.
Trump was so dreaded in DC that reportedly anybody experienced expressing a willingness to move to the WH for the outsider president was shunned. He ended up with slim pickings and the vetting is so damn slow and ongoing that it actually never ends.
