Donald Trump upstaged by a Christie -- again?

MIDTOWN, Manhattan (WABC) -- Once again, GOP presidential candidate Donald Trump has been upstaged by a Christie during a speech.

But this time it's the New Jersey Gov. Chris Christie's wife, Mary Pat.

Social media went wild Tuesday night over her facial expressions.

Many thought Mary Pat Christie rolled her eyes and then smirked as Trump railed against Democratic frontrunner Hillary Clinton.

The analysis went viral, but perhaps she was just trying to avoid the blank facial stare that got her husband into so much grief, the last time he stood behind Trump.
