Tucker Carlson had Democratic strategist Joshua Galper on his show Thursday night, and the two went head-to-head over Susan Rice’s refusal to testify before a Senate subcommittee about Russia’s role in the U.S. presidential election.

Galper says she shouldn’t testify because he doesn’t “believe she will have the answers,” to which Carlson retorted: “Ask her questions. She’s not afraid to talk. She’s on TV all the time, making up stories about Benghazi, or talking about pulling the redactions off names. I just don’t get it. Why not more?”
