[Thomas A. Clawson Diary]
"At 10 A.M. today in a Special Meeting in the Temple of the Council of the Twelve and Presiding Patriarch the First Presidency was reorganized with Heber J. Grant President and Anthon H. Lund and Chas. W. Penrose as his Counselors. Anthon H Lund was set apart as President of the Twelve and Rudger Clawson as Acting Prest of the Twelve Apostles. This is perfectly satisfactory to me and I am quite sure that no matter how energetic and forceful Heber may have been in some of his political views and in his likes and dislikes the Lord will modify and mellow him down and prepare him for the great responsibilities he is called upon to assume."
