The Trump administration is a murky world.
US intelligence agencies have already said the Russian government tried to help Trump win the election. That, they said, is fact.
Now, a big development. The first big moves as Special Counsel Robert Mueller looks into the Trump administration's links to Moscow.
Paul Manafort, who headed up Trump's presidential campaign, has been charged with conspiring to defraud the US - this is in his dealings with pro-Russian Ukrainian politicians.
Manafort had some pretty shonky dealings with the Ukrainians and laundered millions of dollars for his efforts. Some $75 million went through his accounts, apparently. He allegedly banked about $18 million of that. He apparently offered Russian billionaires, who were close to Putin, private briefings on the Trump campaign too.
