Yvonne, Where did this come from? I found a ton of articles placing him in Portland. I found nothing placing him in Washington I found an article including a database of those arrested to date due to the capitol inserrection,his name does not appear. 19 pages https://www.insider.com/all-the-us-capitol-pro-trump-riot-arrests-charges-names-2021-1
You can see from the pictures that he is at the capitol, and he is wearing a Q shirt to try and look like a Trump supporter.
