Trump and his toadies are going well beyond "exploring his legal alternatives". Some of the things they have done are actually against various state and federal laws. If we don't want this happening again, we need to prosecute where laws have been broken.
This is exactly why ol' Joe needs to investigate the Trump Administration - even though ol' Joe doesn't want to.
Obama let W off the hook for war crimes and many Americans are still pissed about that! Unfortunately, if ol' Joe doesn't investigate Trump and hold him and his cronies accountable, the Republican behavior, already outrageous, will become even more outrageous than it is today.
