I am very familiar with the layout of DC (I went to college in northern Virginia) and while you are right that all of it is in walking distance, let BLM tempt you to go to the WH, but ignore them.
The WH is a distraction.
Anyone that encourages pedes to go anywhere but the Capital building is trying to ruin us.
Do not get sidetracked or divided.
We need to go to the Capital building.
Not the SCOTUS.
Not the White House.
Not anywhere else.
Thank you!!!
