“All single-sex facilities in the Capitol and House Office Buildings – such as restrooms, changing rooms, and locker rooms – are reserved for individuals of that biological sex,” he said in a statement. “It is important to note that each Member office has its own private restroom, and unisex restrooms are available throughout the Capitol.”

What I find most interesting about all this is that trans women have been using women's restrooms in the Capitol and the House and Senate office buildings and the White House and the Pentagon for many years now, including during all four years of the Trump Administration.

Under Donald Trump's leadership, trans women were permitted to use women's restrooms in federal buildings in D.C. and there was never any issue.

I have attended hundreds of political events in D.C. over the years and used the restroom at many of them, including in all the buildings listed above.

I have washed my hands countless times at the sink next to conservative and Republican women and even had pleasant and brief conversations with many of them.
There’s never been an issue. Because the whole point of going to the restroom is to do your business in a private stall and then wash your hands and maybe touch up your make-up and, on occasion, with friends, there might be conversations at the sink.

That’s it. I’m sorry there’s no mystery here. It’s pretty straightforward and banal.
