If the Trump Administration actually defies the orders

[The Velveteen Ocelot]

8. We haven't seen anything close to this since Watergate

when Nixon was ordered to turn over the secret tapes. Because Nixon had become so weird and paranoid by that time there was a lot of concern that he'd refuse to turn over the tapes, which would produce a similar executive vs. judicial branch conflict. But Nixon acknowledged the validity of the order and produced the tapes after the Supreme Court finally ordered him to do so - even though he knew they would ruin him. Even Tricky Dick had more integrity than Trump and his orcs.

Theoretically the courts could hold whoever is named in the order in contempt. Whether that would be civil or criminal contempt depends on the particulars (that gets complicated). In civil contempt cases the contemnor is usually ordered to comply or pay a fine; in criminal contempt cases they could go to jail. I wonder how many agency officials are willing to go to jail for Trump, and I wonder whether we will eventually see another "Saturday Night Massacre" where officials refuse to obey the president and are fired or resign.

(For you young whippersnappers who don't remember Watergate, the special prosecutor, Archibald Cox, issued a subpoena to Nixon to get copies of the secretly-recorded Oval Office tapes, but Nixon refused to honor the subpoena. The next day, which was a Saturday, Nixon ordered the Attorney General, Elliot Richardson, to fire Cox. Richardson refused, and resigned in protest. Nixon then ordered Deputy Attorney General William Ruckelshaus to fire Cox. He also refused and resigned.)
