As the week’s crazed news cycle finally seems to be slowing down—maybe? Please?—late-night hosts had a chance to catch up Thursday night, as they each ruminated on the Donald Trump scandals that have unfolded over the past four days. In particular, the comedians zeroed in on new player Robert Mueller, who was appointed as a special counsel to investigate the Trump campaign’s potential ties to Russia. It’s an unusual appointment for an unusual presidency—but as Seth Meyers noted on Late Night, it was also surprising for another reason.

In a way, Mueller’s appointment fulfills a promise Trump made time and time again during the campaign—to appoint a special prosecutor to “look into” Hillary Clinton’s “situation.”

“It’s literally the only campaign promise he’s actually kept,” Meyers said. Given Trump’s repeated warnings about what would happen to the country if its president—hypothetically, Clinton—were under constant investigation, he added, “It’s almost like Donald Trump is a time traveler sent to warn us about himself.”

On The Late Show, Stephen Colbert couldn’t help but smirk at the situation: “You know, the word ‘dumpster fire’ gets thrown around so casually these days, but when a special counsel gets appointed to investigate your administration just four months in, that’s a new high in low. . . This is a snowball just at the top of the hill right now, if the snow were brown and came out of the back of a bull. Don’t get in its way, is what I’m saying.”

In truth, Colbert said, Mueller’s appointment is Trump’s own fault—after all, when his administration “tried to throw [Rod] Rosenstein under the bus” by saying he was behind firing James Comey, they forgot one important thing: “As deputy A.G., he’s actually the bus driver,” Colbert pointed out. “Next stop, Indictment Avenue!”

And Trump should be nervous, Colbert added, because Mueller is in many ways his worst nightmare: “a competent adult who owes him nothing, and who, I’m guessing, has not seen The Apprentice.”

Mueller’s reputation precedes him: he’s well-liked on both sides of the aisle, and is considered to be highly capable—as proven by the fact that his term was extended two extra years beyond the usual tenure. “Forget investigating the president,” Trevor Noah suggested on The Daily Show. “Just make this guy the president. Seriously. Good at his job, and everybody loves him? He’s like a reverse Donald Trump. I bet his hands are huge!”
