I'm not a political person, I try my best to stay away from that mess but the only thing you can do is set a standard for your ministry concerning timeliness, holiness, investing in your singers on a personal and spiritual level (besides just asking them to sing or play) and things will fall into place.
People will respect you for your honesty and reliability and know that the people under your ministry will grow and be blessed by your humility.
