David Green, founder and CEO of the arts-and-crafts chain store, said he will vote for Rubio this week in his home state of Oklahoma, which is one of a dozen states holding primaries on Super Tuesday.

“Marco Rubio has impressed us with his preparation and the way he carries himself. But most importantly, Marco regularly exhibits humility and gives the glory to God,” Green wrote in a statement.

“I don't see humility in Mr. Trump, and that scares me to death,” he said.

Green is a devout Christian who won a key battle against ObamaCare’s birth control mandate at the Supreme Court in 2013. His endorsement of Rubio strikes a blow to Sen.

Green is among several high-profile conservatives who are coming out in support of Rubio in the past week, as Trump is increasingly seen as the party’s likely nominee.

"Our family business that we began with $600 has quite possibly been more successful than Mr. Trump's, but that doesn't make either of us qualified to be president. And unlike Mr. Trump, we give all the credit to God."
