Franken, who was a cast member on NBC's "Saturday Night Live" prior to his time in the U.S. Senate, has been tweeting his support for Clinton in the lead-up to the Minnesota caucus.
In the video, Franken responds to criticisms about Clinton's campaign and, uh, "Mad TV."
"'Mad TV sucked,'" Franken read. "OK, I'm gonna say that was a joke."
Franken also jokes about the "establishment matrix" and talks about his work with both Clinton and her rival, Sen. Bernie Sanders (I-Vt.).
