Former Republican presidential candidate Ben Carson says he was “personally very disappointed” to hear House Speaker Paul Ryan withhold his support for Donald Trump as the Republican presidential nominee.

Carson tells MSNBC’s “Morning Joe” show that “if we divide the party, we ensure the victory of the opposite party. And we’ve got to be more mature than that.”

Carson, who is helping Trump decide on a vice presidential running mate, said Friday: “I hope Speaker Ryan and many others, as time goes on, realizes that.”

On the vice presidential selection, Carson told an interviewer that if there’s a Democrat who subscribes to the Republican Party’s beliefs, “let me know.”

“This is such an important position,” Carson added. “You don’t want to exclude anybody just on the basis of one characteristic.”
