Donald Trump apparently upset his fans on the alt-right message board 4chan during the first presidential debate Monday night, when he characterized the perpetrator of the hack on the Democratic National Committee as probably "someone sitting on their bed that weighs 400 pounds." One anonymous user posted an image titled "fat-computer-guy.gif," alongside the comment, "[Your face when] Trump calls you out for being a 400-pound hacker." Another asked, "Which one of you 400lb a** holes hacked the DNC." 4chan users have previously supplied Trump's campaign with some of its favorite controversial memes, but it's safe to say their comments Monday certainly won't be retweeted by any Trump surrogates.
