President Donald Trump’s campaign spent millions of dollars at businesses run by him and his family members over the course of the 2016 presidential election, according to newly filed campaign-finance reports.

USA Today writes the spending totaled $12.7 million and that the largest sums went to Trump’s airline, TAG Air. It got $8.7 million as Trump used his own jet to fly around the country. Another $2 million went to Trump Tower, the Trump Organization skyscraper that housed his campaign headquarters, USA Today said. The spending at Trump properties continued after he won the election. It underscores how much Trump was willing to mingle his political and business operations.
