Maybe the president can't/won't be indicted, but if there is fraud or other illicit activity conducted by the Trump organization, then at least the SDNY has an obligation to look into that.
"If"? What do you mean "if"?
We already know there is fraud and illicit activity. Of like ten different types, most of which have already been prosecuted. E.g. the Trump foundation was dissolved for tax fraud, trump university was sued out of existence for fraud, Trump paid hush money to a porn star, Trump lied on his tax returns, Trump defrauded banks to get loans, etc. etc. etc.
The fact that entire Trump business empire is rife with fraud and illicit activity shouldn't come as a surprise to anyone at this point, which is why I found Cohen's testimony pretty uneventful. Yea dude, we already know the guy's a crook. The only question now is why nobody seems to care, why the republicans in congress are protecting him, and whether or not Americans are content to have a known criminal as their elected leader and symbol of their national virtues.
At this point, ten more criminal convictions by the SDNY or anyone else won't make any difference. He's already been found guilty of tons of stuff, but he's still president until Congress decides to impeach him. He could literally be found guilty of murder and still be president, because it just doesn't matter. He's totally immune to all of it, until after he leaves office. As long as republicans in the Senate still find it beneficial to keep him in office, it doesn't matter what crimes he commits.
