Committee met at 10:30 A.M. [October 23, 1947], the Honorable J. Parnell Thomas (Chairman) presiding.

THE CHAIRMAN: The record will show that Mr. McDowell, Mr. Vail, Mr. Nixon, and Mr. Thomas are present. A Subcommittee is sitting….

MR. STRIPLING: As a member of the board of directors, as president of the Screen Actors Guild, and as an active member, have you at any time observed or noted within the organization a clique of either Communists or Fascists who were attempting to exert influence or pressure on the guild?

MR. REAGAN: Well, sir, my testimony must be very similar to that of Mr. [George] Murphy and Mr. [Robert] Montgomery. There has been a small group within the Screen Actors Guild which has consistently opposed the policy of the guild board and officers of the guild, as evidenced by the vote on various issues. That small clique referred to has been suspected of more or less following the tactics that we associated with the Communist Party…..

MR. STRIPLING: You have no knowledge yourself as to whether or not any of them are members of the Communist Party?

MR. REAGAN: No, sir, I have no investigative force, or anything, and I do not know.” (Points : 4)
