Republicans are furious 'American Sniper' star Bradley Cooper attended the DNC
Cooper was nominated for a best actor Oscar for his portrayal of Navy SEAL Chris Kyle in 2014's "American Sniper." The war movie was a hit among conservative Republicans, so some of them lashed out on the internet after seeing Cooper at the DNC.
In real life, Cooper supports the Brady Campaign to Prevent Gun Violence and donated to Hillary Clinton's run for Senate as well as her 2008 presidential candidacy.
