From the account I read, it sounded like he just came out with it on his own and surprised everyone. Nobody got him on it, but Jug himself, IOW.
It was spontaneous. Alan was saying thank you for being here, you're in our prayers, yada, yada, and Jug said thank you and by the way, Alan, my president picked the right person! He was dead serious. It was priceless!
Yes, he did it on his own. It was on Hannity and Colmes. At the end of the segment, Colmes was thanking him and wishing his family well. And Jug just jumped in and said, "By the Way Alan, I just wanted to let you know that My President, George Bush made the right decision." Colmes, said, "He's my president too, I just don't always agree with him.
