Tuesday night, South Carolina Senator Lindsey Graham made an appearance on Late Night with Seth Meyers, where the talk show host asked if Graham was suprised by how many members in the Republican party don’t accept the science of climate change.

“I know I’m not a scientist… but here’s the problem I’ve got with some people in my party… when you ask the scientists what’s going on, why don’t you believe them?”

Sen. Graham has previously said he would like to address carbon dioxide emissions in a “business friendly” way.
