The Pubs love to point to the mostly Repub investigation in the Senate, which is still incomplete, but has found no direct link between Dotard and the Russians, as per the campaign. Just LOTS of links between his people and campaign, with LOTS of Russians.

‘We were never going to find a document between Donald and Vlad, written in blood, saying Let’s collude, but we’ve found lots of collusion within the campaign committtee and those closest to the president.’

But investigators disagree along party lines when it comes to the implications of a pattern of contacts they have documented between Trump associates and Russians — contacts that occurred before, during and after Russian intelligence operatives were seeking to help Trump by leaking hacked Democratic emails and attacking his opponent on social media. 

"We were never going find a contract signed in blood saying, 'Hey Vlad, we're going to collude," one Democratic aide said.

Wow, I’m shocked. The Pubs refuse to acknowledge obvious collusion between Dotard’s campaign and the the Russians, that ALL US intel claims to exist.
Absolutely shocking. 
BUT we still have the Mueller investigation.....
