be off message

To deviate from or be unfaithful to the official or agreed upon view, plan, or ideology. We just feel like having a spokesperson with such strong religious convictions is a little off message for our organization. The candidate rarely steps outside of a set of carefully crafted responses during these interviews, so it was odd for him to be so drastically off message. If you want to get paid by the company, you can't be off message in your video about their product.
