Bradley Cooper's appearance at the Democratic National Convention has irked some conservative fans of the actor's portrayal of Navy SEAL Chris Kyle in 2014's American Sniper.
Cooper was spotted by TV cameras Wednesday night seated at the convention in Philadelphia alongside his Russian model girlfriend, Irina Shayk.
Others commented that they thought his experience playing Kyle would have rubbed off on him.
Cooper earned an Oscar nomination for American Sniper, which became a blockbuster thanks in part to an enthusiastic reception among conservative moviegoers, many of whom now appear disappointed by his Democratic leanings.
Cooper was born and raised in the Philadelphia area. Meanwhile, a statue of Kyle went up Friday in his hometown of Odessa, Texas.
