Russia Week has finally arrived at The Late Show, where Stephen Colbert has begun airing remote segments shot during his mysterious trip to Russia. On Monday night, the comedian debuted a clip from Red Square to open the show—and then dove in further during his monologue, in which Colbert riffed on a certain domestic scandal currently embroiling Donald Trump Jr.

“This week we’ll be showing you one Russian field piece,” Colbert said during his opening monologue. “I’m sorry, I meant to say two Russian field—my lawyer is telling me it’s five Russian field pieces. I didn’t think you’d find out; the whole week was supposed to be a secret, but somebody leaked it to CBS’s marketing department.”

Once he took a seat behind his desk, Colbert explained how his trip came about before debuting more footage from his stop at Russian late-night program Evening Urgant. “Despite all the Russia talk, we know almost nothing about what average Russians think,” Colbert explained. “So I thought someone should go to Russia and find out. And then I thought of the perfect person: not me. Because, and this is true, my executive producer Chris [Licht] over there back in December said, ‘Hey, do you want to take a trip to Russia?’ and I said ‘Absolutely not.’ And he said, ‘What if I just found out how much it would cost to go?’ And I said, ‘Well, that couldn’t hurt anything.’ And then I was in Moscow.” While in Russia, Colbert said he spoke with people on the street, spent a day with Russian oligarch Mikhail Prokhorov, met with a Russian security expert and Vladimir Putin dissident, and stayed in the Ritz-Carlton presidential suite. “Yes,” the comedian said. “That one.”

Colbert’s stop by Evening Urgant ended, as we saw, with the comedian jokingly announcing his presidency and soliciting help from the Russians with his campaign. But before that, the two chatted briefly about Russia and its relationship to the U.S.—and played a drinking game called “Russian Russian Roulette,” in which the bullets are replaced by shot glasses of vodka. And they’re all full.

Who knows what’s in store for the week ahead—but we’re guessing if Colbert stayed in that infamous Ritz-Carlton suite, that it’s a safe bet he did more in there than just sleep. Here’s hoping it doesn’t take a leaked dossier to find out what that might’ve been.
