Twitter Mocks Christie During Trump's Super Tuesday Speech

Chris Christie sparks a Twitter craze on Super Tuesday.

But when Trump took to the podium and Christie took a prominent position just behind the GOP frontrunner, the chatter on social media quickly turned.

Twitter users were quick to seize upon Christie’s facial expression during parts of Trump’s speech, which many described as sad, scared, or miserable. The hashtag #FreeChristie took off.

There were also a spike in searches for “Chris, Christie, Vice President” during Trump’s speech. Trump introduced the New Jersey governor as a “friend for many years,” and did not dismiss the idea of having Christie as a potential running mate saying, “he’s got the talent.”
