Refusing to turn over the classified documents when instructed to.

Establishing that Trump knowingly removed documents which were classified is a much harder burden to prove than refusing to return them when ordered.

Imagine a cop stopped you with a stolen backpack. In order to prosecute for the theft of the backpack he would have to prove you took the back pack or you received the back pack knowing it was stolen. However if the cop informed you that the backpack was stolen and he had to recover it but you refused he then has pretty much all he needs to make a theft case against you because the cop knows you have knowledge it is stolen and are still keeping it. I am sure being classified does make it a little more complicated but my example illustrates why using this one charge alone makes the prosecution so much simpler than proving he moved the boxes, made misleading statements, tried to delete security footage, etc.

Just left hpd. When I told them about the email, they didnt know why I needed to show my letter again. At least it only took 10 minutes to get my pistol PTA and get the rifle registered.
So it's all cleared up

I think the timing is too obvious for democrats to claim they weren't coordinated at some level however I would suspect that there was competition amongst themselves as well so they can get recognition.

Having said that, I think the classified documents case is the easiest to prove. If they had picked one or two specific charges, instead of the dozens they threw at him, they could have made it much easier to get their case to trial quickly. If all they went with was the refusal to return the classified documents they would have had a very easy charge to prove

I think the classified document case does have actual merit to it though unlike the others which are really stretching to justify a charge.

When I went through gas mask training, we had to stand in a small house with our masks on while tear gas was released to test the seals on our masks.  Then one at a time, we went up to the instructor, removed our masks, counted to 10 out loud, and left.  I luckily didn't get hit by the gas when I took my mask off.  However, on the bus back to the squadron HQ, I was sitting behind someone who opened their window.  The draft blew the tear gas particles on his jacket into my face, so I got to experience the sensation AFTER my training was over.
