Comer: The way that the Bidens have set this up; there's no business. President Carter's brother got the money directly from Libya. And Joe Biden ironically was on the committee that investigated President Carter's brother when that took place.

Reporter: You said there is at least nine Biden family members…when are we going to learn about the other six? Who are they?

Comer: Joe Biden's son. Joe Biden's brother, Joe Biden's brother's wife. Hunter Biden's girlfriend. Hunter Biden's ex-wife. Hinter Biden's current wife, and three children of the president's son and the president's brother. We're talking about a grandchild, that's odd. Most people's grandchild doesn't get a wire from a foreign national or anything like that.
