A look at some of what's been learned about Trump during the campaign:

— TAX TURMOIL. Trump is the first presidential nominee in four decades to refuse to release his tax returns. The secrecy has spawned speculation that Trump doesn't pay federal income taxes, isn't as wealthy as he claims or is hiding something else about his business entanglements. The intrigue deepened when The New York Times reported that Trump lost so much in one year that he could have avoided federal income taxes for as many as 18 years. Trump subsequently admitted that he had paid no federal income taxes for many years.

— TV TURMOIL. From the outside, NBC's "The Apprentice" was an instant hit that helped turn Trump into a household name, even if its ratings did slip over time. Insiders told AP that Trump repeatedly demeaned female crew and contestants over the years, rating women by the size of their breasts and talking about which ones he'd like to have sex with. None of that made it into the show, of course. But the revelations added to persistent questions about Trump's behavior toward women.
