Does Donald Trump use spray tan?
Jason Kelly, a makeup artist, has worked with the President and he says there's no sign of him using fake tan.

Does Donald Trump wear makeup?
In a famous photo of President Trump and Canada's President Trudeau, a gust of wind blew Trump's hair away from his forehead exposing a large section of pale skin, and what looked suspiciously like a tan line.

Why is Donald Trump's face orange?

The truth about Agent Orange is far from closed.
