Sens. John McCain and Barack Obama will make a joint appearance onstage with the Rev. Rick Warren on August 16 at his church in Lake Forest, California, for interviews on decision making, HIV/AIDS, poverty and the environment, The New York Times reports (7/21).

According to the article, the forum will likely be the only time the presidential candidates appear together before their party conventions in the end of August.

“Since I'm their friend, I'm not going to give them any ‘gotcha' questions,” Warren said, adding that a typical query would be, “What's the most difficult decision you've had to make, and how did you make it?”
