Hillary Clinton "convinced" Trump associates colluded w/ Russia

Hillary Clinton, whose book "What Happened" is out today, tells USA Today she's "convinced" that some Trump associates colluded with Russia in the 2016 election:

"There certainly was communication and there certainly was an understanding of some sort... Because there's no doubt in my mind that Putin wanted me to lose and wanted Trump to win. And there's no doubt in my mind that there are a tangle of financial relationships between Trump and his operation with Russian money. And there's no doubt in my mind that the Trump campaign and other associates have worked really hard to hide their connections with Russians... I happen to believe in the rule of law and believe in evidence, so I'm not going to go off and make all kinds of outrageous claims. But if you look at what we've learned since (the election), it's pretty troubling."
