When it comes to the premise that leftist activists are dumping algae into the reflection pool, I could see it going either way. I don't put it past Trump to make that claim, but I also don't put it past leftist groups doing this sort of thing since they will do anything to go against Trump because they cannot accept him getting any sort of win.

Given the past case of the suspicious wildfires years ago, I am leaning towards the latter possibility.
