Given the polarizing nature of the current president’s personality and demeanor, it should be no surprise that he attracts a LOT of protestors. There are always protestors outside the White House – for as long as I can remember, there was a 24/7 anti-nuclear weapons vigil in Lafayette Square, going back to at least the Reagan administration. The woman who spearheaded that protest has since died, so now the round-the-clock vigil encampment is immigration themed, if I recall correctly.
I don’t usually attend protest rallies or photograph them, given that they can be very sensitive events and I don’t want to be associated with anything that might go wrong when two opposing groups confront each other. Fortunately this is a rare thing in DC, but it does happen.
I was out playing tourist/tourguide with some out-of-town friends over the Martin Luther King Birthday holiday. We walked from the Air and Space Museum up Pennsylvania Avenue past the White House, then on to the Washington and Lincoln Memorials before finishing at the MLK Memorial. Outside the Renwick Gallery there was this character:

Inside his white box, he was playing the harmonica through a portable amplifier. There was no discernible connection between his song choices and the overall theme of his demonstration, so I don’t know to what extent he was consciously protesting, making social commentary, or just serendipitously expressing the zeitgeist because his meds were wearing off.
Outside the White House was a different matter, and a much more pointed display of discontent. This was right after the president had made his “shithole countries” comment, so much of the signage centered around that.

I chose this image because of the profoundly ironic juxtaposition of the happy tourists posing for a family photo in front of the White House with the protesting woman in front. This is something you will experience here in Washington that I don’t think you see many other places – the cognitive dissonance of “oh look, we’re jazzed to be here!” immediately adjacent to “I’m righteously indignant and I’m not going to take it any more!” expressed over the exact same subject.

One good thing about photographing protestors is that if you want to get better at “street” photography, they’re a great subject to practice on, because they absolutely want their pictures taken to get their message out to the larger world.
