It’s a non stop assault on everything

Mr Trump has made several decisions and issued orders that have drawn a rebuke from the courts, ie the judicial a branch. 

That is their job. To provide part of the checks and balances on the executive branch. 

However, Mr Trump has decided that he simply doesn't care, and doesn't have to listen to them as only his actions matter. 

When it comes to the alien enemies acts, he is misapplying the context to suit his actions. 

And as another branch of government (ie the legislative branch, using basic civics) you are the third part of the checks and balances.  

It is your sworn duty to uphold the constitution.

When Mr Trump does something that oversteps the bounds of his office, or in this case misapplies acts created by the legislature (even if it was before your time) you need to hold him to account for it. 

And when he violates his oath of office, and ignores the constitution, then it is your job to remove him from office. 

That is what our founding fathers set forth in the document you swore an allegiance to. 

Do not let him act like a king or tyrant. 

Do your job and support the judicial branch in calling out his actions.
