It's just another way the swamp is trying to tie the executive branch's hands because Trump isn't playing their game. It is already a crime is to cover up or impede an investigation. When the crime is committed then you charge him with it and prosecute him. You don't need appointed and not elected court judges to decide what the President can and can't do. These judges aren't held accountable to the people. They can have an agenda especially depending on if a Republican or Democrat appointed them as a judge.
