The US intelligence community had determined that Russia interfered in the 2016 election by January of this year and briefed Trump. 

Mueller is investigating - amongst other things - whether the Trump Campaign colluded with the Russian government. 

As to the former point, Trump has taken great pains to be less vigorous in damning and punishing Russia. As to the latter point, Trump has called any allegation of campaign collusion a hoax.

It is important to differentiate President Trump from the "Trump Campaign".

It is possible that the Trump Campaign colluded with Russia. I am not qualified to say whether it is probable.

But I can say, that Trump calling it a hoax, isn't necessarily an admission of guilt. It might just be his ego. It is consistent with Trump's personality to not admit (a) he got unwitting help from Russia when Trump himself believes he won because ... well he is great and he did it by himself and (b) the same would go for members of his campaign staff helping Russia.

I know some anti-Trump voters are drawing a direct line between Mueller's investigation and Trump. They may ending up being right. But right now, on this day, they are engaging in wishful thinking.

I am anti-Trump because of a difference in politics. Specifically, I loathe his actions that are contrary to his position as America's head of state, his profound use of hyper-identity politics and most of his policies.

As such, I believe the best course of action, is to vote in the next general election. I would advise other anti-Trumps to think the same way. If every anti/never-Trump voter would vote - they didn't before - Trump would be out of office in 3 and 1/2 years.

A democracy requires citizen action. Not simply hoping the DOJ will do the work for them.
