“Vince [is] not merely interested in Dr. Paul’s philosophy but he also graciously invited Dr. and Mrs. Paul to the premier of his film ‘Couples Retreat,’” according to Paul’s 2012 National Campaign Chairman Jesse Benton in a statement.

The Pauls did attend the premiere of Vaughn’s film “Couples Retreat” in 2009.

Vaughn also wrote an endorsement for Paul’s book “End the Fed” in 2009, writing: “Everyone must read this book–Congressmen and college students, Democrats and Republicans–all Americans.”

Vaughn is not Paul’s only celebrity fan. Iconic singer Barry Manilow told The Daily Caller earlier this week, “I agree with just about everything [Paul] says.”

LPAC is an annual forum for "freedom activists" featuring mostly libertarian speakers.
