He was held in Contempt of Congress for not responding to a subpoena - this is likely just the follow-up indictment to go along with it.
Correct he’s been taken into custody for ignoring a congressional Subpoena. He should have complied I mean it’s not like he’s a liar or covering up something so you’re just gonna run in and give them both barrels of the truth, figuratively speaking of course, if he’s really in the right… I doubt if I could do that as a private citizen, ignoring subpoenas Next will be Mark Meadows by mid summer I suspect, and probably others… There’s always the fifth amendment
