He was the one who got James Clapper to lie and state to Congress that he was "not wittingly" collecting American phone records in bulk. Though I do not believe he has ever come out and explicitly stated his views on the matter, his actions do suggest that he is against backdoors in all circumstances. EDIT: Another reply has provided a quote that shows Wyden's views on backdoors. He appears pretty strongly against them.
