I would have thought this is a big deal, but I'm not American and not up to speed with the law there.
Surely if he simply refuses to turn up to a Congressional Hearing, or refuses to hand over documents requested by Congress (??) that's tantamount to a challenge on the Government?
Isn't it punishable?
I know if I was ordered to turn up to court in my country, and didn't, I'd be arrested immediately.
Did Jeff Sessions turn up with the unreacted documents last Thursday, as instructed?
Seems odd to me, but there's obviously something I don't get about the hierarchy over there….
