Also, not actually true!
There were claims that she received debate questions weeks in advance, which are a complete and total fabrication by a probably-not-innocent prank website.
There were separate claims that she received debate questions shortly before the town hall debate. And there was an effort to do so from someone outside of her campaign - but the questions that were provided were not the ones asked, so.... It's false to say she received some debate questions in advance.
