politfact is not really a good source. Trump has some financial involvements that should be questioned, but this isn't really enough. Indictment doesn't mean guilty as I believe.

If there had been something, we would have heard about it non-stop.

Well, Trump had 6 key people indicted, including his lawyer and his campaign manager, on 81 charges and several convictions / guilty pleas. Clinton had 2 indictments and 1 conviction, while Obama and Carter had 0. Which administration out of these would you say was the least "clean"?
