An ex-GOP lawmaker has heard enough about phantom left-wing saboteurs at the Lincoln Memorial Reflecting Pool, and he is pointing at the only suspects who fit the evidence: the people Trump hired to clean it.

In a series of posts and a new video, former Republican congressman Adam Kinzinger dismantled the administration’s vandalism narrative by accepting one piece of it. Yes, he conceded, chemicals were used on the pool. The catch is who used them and why. “Just for those who are saying there was chemical sabotage to peel the paint in the reflective pool, you’re right,” Kinzinger wrote. “It’s just, you guys did it to kill the algae.”
