By law the Director of National Intelligence should have an intelligence background. Collins doesn’t have that. He’s never worked for any intelligence agency, did not work in intelligence in the military, did not serve on an intelligence committee while in the House. If he’s appointed as acting then he’s out in a year. If he’s nominated for permanent post he’ll never be confirmed.
I think that nails it.
Still, I hope Trump can find a way to stop Collins from challenging Loeffler for the Senate seat, and do it soon.
Got a cite for that? The limitation you state isn't in 50 USC 3023.
