Just off the top of my head?
Putin hacked the election to help trump. According to our intelligence agencies' assessments.
Trump on the campaign trail asked the russians to release more hacked material on hillary.
The day trump's "pussy grabber" video was released, the russians immediately released hillary emails to distract from the trump story.
Trump's original campaign manager previously was paid 10 million per year to promote putin's interests in the USA.
Jeff Sessions, Carter Page, Jarrod Kushner, Gen Flynn ALL concealed or "forgot to mention" contacts with russians.
Trump removed the part of the republican platform that opposed putin's invasion of the ukraine. It was the only part of the platform he took any interest in.
Trump picked Putin's favorite oil exec to run the state department. That exec is now in the process of firing anyone in the state dept who has spent their careers working to contain russia's aggression.
Trump picked Putin's favorite general as national security advisor.
Trump bought an estate in florida for $50 million and then turned around and sold it to putin's buddy for $100 million. Just a great businessman right?
Trump is the first president in decades to not release his tax returns. Wonder why.
Jarrod Kushner tried to set up a backchannel to talk to russia without any other parts of the government knowing about it. If you think this is standard procedure, you're wrong. He didn't do this with any other country.
Trump leaned on Comey to end the trump investigation, when he didn't obey he was fired.
And there's lots more if you cared to join the real world:
The many paths from Trump to Russia
But I suspect you will cling to your pathetic delusions that it's all just a bunch of coincidences and liberal media conspiracies.
