Either way, those pictures have a very high likelihood of causing reputational (and, by extension, financial) harm by alienating a chunk of her fan base who may think she endorses his viewpoints. Especially when paired with his post implying she endorsed him.
I bet she could even argue that him forcing her to take a position publicly against him also constitutes financial harm, because of the possibility of it alienating any of her fans that were Trump supporters.
Well, as a millennial, I also have little trust in Congress or the presidency, so this also checks out.
