(Why did she have a microphone in her face )
What are you talking about? She didn’t!
It’s the awkward sentence structure. Just making fun of that.
Almost everyone would write “...who hit President Trump IN THE FACE with a microphone..”
Say it were “...who hit Trump with a pen in the hand...” you’d think she was holding a pen in the hand when she hit Trump, not that she used a pen to hit Trump’s hand.
