"When I accepted the invitation to do the president's inauguration, who I clearly don't agree with, just like I would accept an invitation to Larry King or whatever, it's because I knew every--on that inauguration--every national leader, every king and prince around the world was watching that show, okay. And I thought if I have a team that's in a country and they get in trouble, they can hold up a picture, This is the president of the United States and this is my pastor. It may be able to get them out. So it really had nothing to do with national consumption. My motivation is really all about mission." (source)
So, you can point to a picture as evidence of your 'connections' -- to imply or say you have the backing of the guy(s) in the picture. Nice. Huh.
