All of these charges, at this stage, relate to Manafort's actions before he came on board with Trump. And Manafort resigned from the Trump campaign last year, after his links to the Ukraine emerged.
Rick Gates, a longtime associate of Manafort's and another Trump campaign official, has been charged with the same - money laundering, tax evasion, fraud and conspiracy against the US.
And, George Papadopoulos, one of Trump's early foreign policy advisers, pleaded guilty to making false statements to the FBI about contact he had with the Russian government.
It's explosive stuff - but perhaps not surprising.
This is what happens when big business enters politics. Millionaires - and in Trump's case, billionaires - who are used to doing deals, not doing democracy.
Donald Trump's been on Twitter this morning. He says "Why aren't Crooked Hillary and the Dems the focus?"
Well, answer this. Why isn't policy and improving the lives of Americans and "Making America Great Again" - why isn't that the focus?
Instead, the focus has been on what must be the most morally bereft and ethically corrupt political administrations in the western world today: an investigation to uncover some of the shonky practises that undermined American democracy. Fat cats getting fatter. Fat cats pulling strings to ensure, whichever way possible, they would take over the White House.
The Trump administration has never and will never understand its mandate: to work for the American people who voted them into government.
Instead, they do what they've always done. Work for themselves. And it is only they who will benefit from that.
