Chris Christie won the Twitter primary on Super Tuesday.
After the New Jersey Governor and former presidential candidate gave a somewhat flat-sounding introduction to front-runner Donald Trump, Twitter users could not stop talking about Christie.
In a wide-ranging speech-slash-press-conference, Trump even mentioned Christie twice, once joking about people moving out of New Jersey and once calling him the exception after saying that politicians don't keep their promises.
But it was Christie's expressions and body language that got attention, causing #freeChrisChristie to trend on Twitter, according to search firm Dataminr.
Here are some representative tweets.
