I don't know whether NM has said anything, or what her opinion is - you should ask her. And McBride, and all the other representatives while you are at it.
Obviously I think it's very wrong, but I'm curious to know what's your objection to Trump going into the women's changing room, given that you think male people should be allowed in women's single sex spaces?
Trump, McBride, Zooey Zephyr and ZZ's partner are all male and therefore will all be excluded from women's facilities in the Capitol, along with all the other male people, thanks to NM's bill which has now passed.
