Along with showing support for Republican presidential candidate Mitt Romney, the 82-year-old tough guy also spoke about the current presidential administration by addressing an empty chair that he told the crowd was occupied by President Barack Obama.
Check out the entire speech.
His gag of talking to an empty chair inspired a Twitter account named @InvisibleObama that had garnered more than 25,000 followers before midnight Thursday.
The Obama campaign immediately shot back on Twitter Thursday night with a photo of the President sitting in a chair in the White House. It read, referring to Eastwood's empty chair, "This seat's taken."
CNN's Piers Morgan told the Hollywood Reporter that "He came off like the slightly crazy uncle at the Christmas party who’s had one too many sherries and doesn’t quite get it."
Romney’s spokeswoman told Piers Morgan backstage, "He's an American icon. You can't look at him at through the same political lens that you would other politicians. He's Clint Eastwood."
Democrat Kirstie Alley tweeted, "I just saw Clint Eastwood's speech and I LOVED it!! Funny as hell & on point!!"
Eastwood is starring in the upcoming baseball drama "Trouble with the Curve,” popping up in theaters September 21.
