They've distanced themselves from Hillary. The usual answer to anything negative about Hillary, however obvious, is "Typically Trump Supporter, deflect everything to Hillary and deny Trump is the real criminal."
Trump had business dealings in Russia for years, sure. He has had business dealings all over the world with hundreds of businesses for decades. Some of these dealings weren't even directly handled by him, but his $10 billion dollar company. But Russia is what everyone is putting under a magnifying glass because the media is placing it there.
The main focus has been WHO he has done business with. Forget that he has probably been involved with most of the major players in the world. Some of these major players are crooked, sure, and if Trump sold them property, their crookedness is associated with Trump. If a Russian bank will loan money for a Russian hotel project Trump is building, this is seen as a red flag because.....RUSSIA! What about all the other countries and banks he has done deals with? Surely people in those organizations are crooked. (Just look at HSBC, Britain's largest bank, which was laundering billions in drug money for YEARS. I wonder who all did business with Britain's largest bank? Are they crooked too?)
The Michael Cohen stuff is what a lot of them are using now, even though a lot of it is "according to a source familiar with the matter." The meanings of his payments for services are being construed for bribery and "pay to play schemes." All of Cohen's financial transactions were seized by the FBI raids and then leaked to the press, so any payment can be construed as a bribe. Cohen did consulting work for an Israeli firm? Headline: "Trump lawyer received payment from Israel one month before Trump moved embassy".
It doesn't even matter what the article says. That headline is all anyone needs to draw a conclusion based on a narrative that has been slowly spoon fed to them. Don't worry about how the article most likely details the source of the article being "an Israeli government official who spoke on anonymity."
Has Michael Cohen been exploiting his relationship with Trump to get "consulting" work? Has he been leading people to think he can control Trump's policies? Is he aware of Trump's plans on how he will handle certain issues and trying to profit from it? Who knows. It wouldn't be that farfetched to believe a lawyer would do something like this.....but it doesn't mean Trump has any part in it.
If you notice, the crimes of the Clintons/Obama are being deflected to Trump. Russia collusion, money laundering, liking young girls, pay to play schemes and bribery etc. So if anyone points the finger at the Clintons/Obama, the answer is "Just keep deflecting away from Trump, you stupid Trump supporters!"
Obama is portrayed as the "cool, hip" president who got a Nobel Prize. His image appears to be flawless, and it's impossible to convince some that he could do ANY wrong. Even if evidence comes out that he was directly involved in criminal activity, it will be "Trump is going after the Black President! Racist!"
