Collusion was found. The Trump tower meeting and then lying about it is an example of collusion. However collusion itself is not a crime. Obstruction of Justice however is very much a crime.
1. Collusion is not a crime.
2. The ONLY reason the Trump Tower meeting took place with the female Russian Lawyer was because Obama overrode his own DHS' BAN on this Russian which prevented her from entering the country. Yes, you read that right - BARRY actively took steps to have the ban lifted so she could enter the country and attend this meeting. (Can you say 'set-up'?)
3. Evidence shows she met with Fusion GPS (and Ohr's wife) the day BEFORE the meeting, the day OF the meeting, and the day AFER the meeting. (Can you say 'set up'? )
4. Comey's FBI knew enough in advance about the meeting (when / where) that they had electronic surveillance set up AND Obama's own personal former CIA Russian Interpreter was there in the room. (Again, can you say 'set'up'?)
5. Trump Jr stated he was led to believe the meeting was about Russian adoptions. When he found out it was not he claimed he texted his Secretary and directed her to call his cell phone so he could make the excuse that he had to leave to attend another meeting. Everything he said happened was proven to have happened. Phone records show 15 minutes into the meeting he texted his secretary and just a few minutes later she called him - he left.
6. EVEN IF HE DID BELIEVE THE MEETING WAS ABOUT POTENTIAL POLITICAL OPPOSITION RESEARCH ON HILLARY,
SO WHAT?! Again, collecting political opposition research IS NOT ILLEGAL. Does anyone needs a reminder at this point that Hillary had purchased a Russian-authored fake news dossier from a Trump-hating foreign spy working with and being paid by the Russians? THAT is okay, but attending a meeting with a Russian lawyer about possible opposition research on Hillary is 'illegal'?
*** ADDED NOTE: Unlike Hillary (and Rosenstein, Clapper, Brennan, Comey, Ohr, etc...) Trump Jr walked away from the meeting WITHOUT ANY INFORMATION HAVING EXCHANGED HANDS (according to everyone at the meeting, to include the Russian lawyer later). Hillary purchased the Russian-authored dossier offered to her, and the Obama agency directors ended up using the information illegally.....but Trump is the criminal?
Bwuhahahahaha.......
