Eastwood was personally invited to speak at the RNC in Tampa by Republican presidential nominee Mitt Romney, but when campaign officials asked for specific information about what he would say in the speech, the star said he was reluctant to provide details.
"They vet most of the people, but I told them, 'You can't do that with me, because I don't know what I'm going to say," Eastwood told the newspaper.
Eastwood revealed that the idea to talk to the empty chair came to him while he waited in the Green Room just minutes before he took the stage. "There was a stool there, and some fella kept asking me if I wanted to sit down," he said. "When I saw the stool sitting there, it gave me the idea. I'll just put the stool out there and I'll talk to Mr. Obama and ask him why he didn't keep all of the promises he made to everybody."
