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.
