I’m thinking it will be some White House or campaign staffer that we haven’t heard from yet. Or a rally organizer, like Katrina Pierson or Amy Kremer. Outside chance it’s Mo Brooks. Probably a relatively unknown staffer, though. Or maybe the guy that had to sweep up the broken dishes and clean the catsup off the walls.
Fun fact - when Trump tried to smear Ted Cruz during the 2016 primaries by having the National Enquirer run a story claiming Cruz had affairs with 5 women. All clues pointed to Pierson as one of them, Pierson denied it.
