And one more

Social media had a field day with Chris Christie Tuesday night after the New Jersey governor displayed some odd facial expressions as he listened to Donald Trump's Super Tuesday victory speech. Christie had introduced "Mr. Trump" in Florida Tuesday then looked like he perhaps had some regrets about doing it as he seemed to stare into the distance while Trump spoke.  The hashtag #FreeChrisChristie began trending on Twitter after Congressman Justin Amash said "Chris Christie just gave what looked like a coerced confession."  Amash also said the event was "staged to look like a hostage situation."
