Clint Eastwood -- Doesn't 'Give a Crap' About RNC Speech Critics

Clint Eastwood says he doesn't really give a crap about the people who ripped his impromptu "chair" speech at the Republican National Convention ... saying he was just expressing his feelings.

Clint appeared on "Good Morning America" this morning ... and the 82-year-old explained one of the reasons he didn't want to give a traditional speech off a teleprompter that night is because "I didn't have my glasses with me ... so I wouldn't have been able to read it."

Instead, he explained ... "So then I’m just sitting there and the guy says, ‘You wanna sit down?’ and I said ‘No, but put that [chair] next to the podium will ya.'"

And a legend was born.

When he was told that Obama is still a fan of his, Clint said, "Well, that's his bad judgment."

As for the criticism Clint has received since the speech ... Clint says, "There is something about the aging process that makes you give a crap less."
