"I'm a big fan of Rand Paul. He and I are good friends. I don't agree with him on foreign policy," Cruz said in an interview aired Sunday on ABC's "This Week."
"I think U.S. leadership is critical in the world. And I agree with him that we should be very reluctant to deploy military force aboard," Cruz explained. "But I think there is a vital role, just as Ronald Reagan did."
During the interview, Cruz pointed out that Reagan "changed the course of history" with his aggressive stance towards Russia, suggesting that perhaps a perspective like Paul's might have led to different results.
To add to the drama, Paul had initially agreed to be interviewed on ABC's "This Week" on the same issue.
According to ABC's Jonathan Karl, Paul backed out at the last minute.
