Funnyman Dave Chappelle is in Iowa stumping for his Democratic candidate of choice, Andrew Yang, ahead of next week’s first-in-the-nation caucus.

Chappelle, who endorsed Yang earlier this month, spoke to reporters in Ames, Iowa, Tuesday ahead of the candidate’s rally, during which he brought the comedy legend onstage to surprise supporters.

Asked what he liked about the 2020 hopeful, Chappelle discussed his enthusiasm for Yang’s signature proposal: universal basic income (UBI), which would give $1,000 a month to every American.

“Dayton, Ohio [where Chappelle lives], has a third of the people there living below the poverty line. If you were to take a poll in Dayton and say, ‘What would you rather have: $12,000 a year or health insurance?’ Everyone’s taking the money. Health insurance is great but groceries are necessary too, and people in Dayton are having a hard time getting the things they need. I started imagining what a universal basic income would do for my community, and it would save it almost instantly,” the comedian said.

Chappelle also highlighted how UBI, which Yang’s campaign refers to as the “Freedom Dividend,” would give people more financial flexibility than current government programs do.

“I like the idea of giving people choices, putting the money in their hands and giving them the choices,” he added.

Chappelle will campaign with Yang in Iowa and South Carolina. He is due in Columbia, SC, Wednesday and Thursday for back-to-back comedy shows. All proceeds from the shows will benefit Yang’s campaign.
