Donald Trump flubs Bible verse during speech at Christian university

If you're going to quote scripture in a room of fervent Christians, you better know your stuff.

GOP presidential front-runner Donald Trump learned that lesson the hard way Monday, when he spoke to students at Liberty University, a Christian school in the heart of Virginia.

After vowing to protect Christians across the globe, Trump read a verse from Second Corinthians — one of the books in the New Testament. But Trump flubbed the name, pronouncing it "Two Corinthians," as it's often written in text.

Students at Liberty University — who were forced to attend Trump's speech if they lived on campus — lit up social media with jokes about his error.

Reporters and political pundits got in on the fun.

The billionaire businessman's visit to the school was likely a ploy to woo Evangelical voters to his camp.

Evangelicals are currently flocking to Trump's top opponent, Texas Senator Ted Cruz, who is leading in Iowa and gaining in Southern primary states with just 13 days until the Iowa caucuses.
