Trump did craft a statement for Jr to read to Congress.  It was a lie and the purpose of that lie was to deceive.

I've seen multiple stories on this, but I don't see your side. Explain it clearly.

We also know that he fired Comey over "that Russier thing"...  
That is obstruction, and is impeachable.  The fool admitted to it on national TV.
As he did with Sessions firing,... and McCabe.  
Also the numerous threats to Rosenstein.
All impeachable.

Impeachment is a political, not a legal, remedy. You could impeach a President for any reason. The President firing Comey is a political move, not an illegal one. He can fire anyone in the Justice Department for any reason anytime he wants. (there are technical limitations which means he actually tells someone else to fire that person as Robert Bork did in Watergate)  

He can direct the Justice Department to stop investigating anyone he wants or he can direct the Justice Department to begin investigation anyone. Those are not illegal actions which is why the Constitution put in the impeachment provision. It's a totally valid argument that the President cannot be charged with obstruction while head of the Justice Department which is his Constitutional role as President.

What is or what isn't impeachable is totally up to the House.

Even the President is not above the law.

Actually, yes, the President is the one person who is in fact above the law in many regards. Proving obstruction as a felony while the President was in office would be a tough chore.

So many details, it's hard to keep track, but we both know there's a lot of dirty going on.
When you pile it up,... it shows that Trump is desperately trying to hide from the facts.

The reality is, any major businessman with interest around the world over a period of decades would be in trouble with this level of scrutiny. I have no doubt about that.

I also have no doubt why Trump will not release his taxes. It would bring too many of his business partners into the light who would rather remain anonymous. That doesn't mean they committed illegal acts necessarily.

Here's my point. If it were shown Trump colluded with the Russians to
hack into and change the vote totals, I consider that treason and he should be shot.

If it were specifically shown Trump made a deal with Russia that said he'd swing billions of construction business to Russia if they'd help influence the election, that's also Treason. But that's a grey area where previous business dealings with Russians could easily be misinterpreted as such. Just because Trump did business with Russians on its face, means nothing. Any international businessman has likely done business with Russia. My company has an office in Russia and a few years ago, I helped that office on a project. It would be easy to label that something its not. I just saw an internal memo today we won a bid for some work in a power generation system in Iraq. If by some stretch, the owners of my company ran for office and you saw that on their tax returns, you could paint that into something it's not.

If it were shown Trump owed a great deal of money to Russia and they made a deal to that go if they helped him get elected and expected favors in return, that's also treason. But since he's been in office, what deals have we made that benefit Russia? So that's unlikely.

If Trump Jr agreed to a meeting to get dirt on Hilary, that means nothing to me. Typical political stuff that I'm not going to get worked up over.
