And why is she always wearing men’s coats or sports jackets?
Very odd.
Fashion is subjective. I think she looks fine. She's not trying too hard unlike Michelle Obama did. Anyway, Joe Biden gave Kamala Harris a job. She was supposed to go to the border. She didn't do that. She may not have wanted to do that. But that's part of the deal of being VP. Joe could send her to a funeral of a President in Congo because Joe "can't make it". But that is what the VP is supposed to do. She represents the President when he is unable to show up in person.
