Donald Trump Jr. posted a video on Twitter Tuesday night showing a black Trump supporter being removed from a Southwest Airlines flight after lowering his mask while he ate peanuts.

“WTF???” President Trump’s eldest son tweeted, along with a video of showing a man being removed from a commercial airline flight. “This is disgusting. I’ve been on a thousand flights in the last few months and everyone lowers their masks to eat and drink. I did it on a southwest flight earlier this week.”
