The presumptive Republican presidential nominee has been on the campaign trail for a year now, and federal finance reports over that time detail a campaign unafraid to co-mingle political and business endeavors in an unprecedented way.

Wealthy political candidates in the past have walled off their business from their campaigns, but Trump embraces his companies.

Public documents indicate his revenue has risen along with his presidential aspirations.
