Interesting, to start General Conference, following the hymn and prayer, President Uchtdorf explained how and why we sustain Church officers and the Church seems to have changed the way in which sustainings occur. They had the First Presidency stand and sustain the President, First Presidency, and Quorum of the Twelve. Once that was conculded they had the Twelve arise and sustain the same, then had the first and second quorum of the Seventy stand and sustain, then had the all area seventies, patriarchs, HP and Elders throughout the world stand and sustain the same, following that they had the Aaronic Priesthood arise and sustain, followed by the Relief Society, then Young Women and all other members of the Church stand and sustain the First Presidency and Quorum of the Twelve as previously consitituted. It was very interesting and the first time they have done that as I recall. Funny how things change with the changing of a President.
D. Todd Christofferson was called and sustained as the newest member of the Quorum of the Twelve. Elder Christofferson was born on January 24, 1945 in American Fork, Utah. He was called as a member of the First Quorum of the Seventy at the April General Conference, 1993 and in August 1998 he was called to the Presidency of the Seventy. His latest assignment was presiding over the North America Northwest and North America West areas of the Church. In his personal life he supported himself and his family as a lawyer.
Here is an interview Reuters did with Elder Christofersson in 2007.
The members of the Church sustained President Thomas S. Monson, Henry B. Eyring, and Dieter F. Uchtdorf as Prophets, Seers and Revelators for the first time
