Filipkowski is mocking Trump's claim that the Lincoln Memorial Reflecting Pool was vandalized with a boxcutter, asking sarcastically if any arrest has actually happened. Trump has publicly said 5-6 people were arrested, but FactCheck.org and the New York Times both report his administration has provided no evidence to back this up, and experts say the pool's problems likely have other causes. The sarcastic question is essentially accurate — no verified arrests for boxcutter vandalism have been confirmed despite Trump's repeated claims.
