Obstruction of Justice is a serious crime - DUH.
So we're back to that again. Ok, so where did Our President obstruct justice? He never invoked executive privilege. He never invoked attorney-client privilege. He never fired anyone, or interfered with the special counsel in any way.
I suggest you familiarize yourself with Part II of Mueller's investigation report, which details 11 instances of Obstructive behaviour.
Some highlights of what our POTUS has been up to:
1. Pressured FBI Director (Comey) to squash investigation into Trump's top foreign policy advisor (Flynn). Trump subsequently fired that FBI Director under false pretenses over the Russian interference investigation. The firing triggered assignment of Special Investigator and Flynn eventually pled guilty.
2. He pressured AG (Sessions) to unrecuse from Russia investigation, publicly declare it unfair, and to limit it's scope to only FUTURE election interference.
3. He ordered White House Council (McGhan) to procced with removal of Special Investigator (Mueller), when McGhan refused the order and started packing his stuff, Trump backed off, but ordered McGhan to enter false record of Trump never having ordered removal of Mueller.
4. Trump was tampering with witnesses by pardon dangling Flynn, Manafort and Cohen
Here are the 11 instances of potential obstruction of justice by Trump outlined in the Mueller report
It's true that Trump failed to stop Flynn's investigation and to remove Mueller - but that is irrelevant, the only reason it didn't happen was due to the REFUSAL of his corrupt orders by his subordinates.
