FOUR billion would be the dif between Trump's claim and/or Wikipedia source and the 2015 billionaires list linked. MORE THAN DOUBLE a diff in the claim.
The kind of folks who trust Wikipedia, trust Trump, apparently.
Wikipedia may be okay with you on this forum -- but it's OUT for me on any forum except if it's a paid gig and I'm really desperate and it's only cotton-candy info that doesn't matter anyway. But to really on Wikipedia for really important info -- bad idea. Beware.
Whatever
