How Bernie Sanders Got Rich Selling Books (just the facts)

[Autumn]

15. The problem you have is that the book that the campaign spent $444,937.50 on in 2015 ,

Outsider in the White House, was published in 1997, republished by Verso Books, in 2015 and given out to campaign donors. The books that made him money were published in 2016, 2017, 2017.
Where are the documents showing he had his campaign pay for the last three books that made him a millionaire?
All you have listed are the raw expenditures file from the FEC web from 2015. Nothing after that.

Are you claiming he went back into time to 2015 make money off his three bestsellers that were written and published in 2016, 2017, 2018? Cause that's pretty fucking awesome if he can do that.
