On Monday night’s episode of “The Daily Show,” Jon Stewart covered the fiasco that is President Donald Trump’s renovation of the Lincoln Memorial Reflecting Pool, which is now infested with algae.

Stewart opened the show with CNN soundbites, which explained that the pool’s high phosphate levels invited a “significant algae bloom” that turned the monument into “a sea of green.”

“That is really fucking green,” Stewart joked. “That shit’s neon green! Did they replace the water with Mountain Dew?”

Through another pair of soundbites, “The Daily Show” revealed that one of the companies working on the renovation won the job through a “no-bid contract,” and was “owned by a trust run by Republican donor John Cafaro.” After revealing a photo of Cafaro to his audience, Stewart joked that he looked like “an extra in ‘Guys and Dolls.’”

“That’s the pool guy? Does Donald Trump do business with anyone normal?” Stewart exclaimed. “Looks like Donnie Brasco got stung by a bee. I’m sorry, to be fair, that’s gotta be an old picture from like, the ’80s when Gomez Addams was all the rage.”
