Comedian Stephen ColbertStephen Tyrone ColbertF-bombs away: Why lawmakers are cursing now more than ever Stephen Colbert on Trump: 'He's trying to invite us into this madness' Biden's personal grief comes to forefront amid mass shootings MORE caught Sen. Rand PaulRandal (Rand) Howard PaulGraham promises ObamaCare repeal if Trump, Republicans win in 2020 Conservatives buck Trump over worries of 'socialist' drug pricing Rand Paul to 'limit' August activities due to health MORE (R-Ky.) off guard late Wednesday night, joking about marijuana.

“You’re not going to talk about pot, are you?” the GOP presidential candidate asked Colbert when the late-night host quizzed him about drug policy reform.


“Are you a cop?” Colbert retorted. "Because if you’re a cop, you have to tell me. Otherwise, this is entrapment.”

“I thought we said before we would not talk about pot, Stephen,” Paul replied, wiping his brow with a kerchief.

“You tried to sell me pot backstage,” Colbert quipped. "Sorry, you tried to sell me on the idea of changing sentencing guidelines for pot backstage. I should have finished the sentence.”

Paul then turned more somber when discussing GOP presidential front-runner Donald Trump.

“I think, all kidding aside, that there’s a certain seriousness to leading a nation of 300 million people,” he said of the outspoken billionaire.

“He says, ‘Of course we’ve got a nuclear triad and our biggest problem is we haven’t been using it enough,’” Paul continued.

“We’re kind of making light but that shouldn’t be made light of. You want someone who has judgment, someone who has wisdom and someone who has restraint.”

Rand Paul also discussed his father, former Rep. Ron Paul (R-Texas), a two-time GOP presidential candidate.

“He’s doing great,” he said. "My dad is indomitable. We go home and he out-walks us, he out-rides us on the bike. He’s in great shape.”

Paul additionally joked about how his fiscal conservatism defines his spending habits, given he performs his own haircuts.

“I’m conservative, man — I’ve got to save money,” he said. "I have three kids in college.

“It’s a bit random,” the Kentucky lawmaker added of his barber skills. "Sometimes there’s drinking beforehand."
