It’s a broader sense of the word “ministry”.

https://en.wikipedia.org/wiki/Christian_ministry

Christian ministry is the vocational work of living and teaching about faith, in the hopes of increasing the population of God’s people done by the church, church officials, congregational members, and Jesus followers. The Cyclopedia of Biblical, Theological, and Ecclesiastical Literature defines Christian ministry as “to denote a devotion to the interests of God’s cause, and, in a technical sense, the work of advancing the Redeemer’s kingdom”.[1] All ministry may fall under the call of, the Great Commission, that Jesus presented to his disciples to continue the spread of the Gospel.

While the spread of the Gospel is every believers purpose, the primary and only vocation of the bible is to live a life aligned with God, as his children, towards the purpose of displaying the love of Jesus through one’s actions and decisions. Some see vocation as one’s true calling professionally, yet others see it as a furthering of God’s kingdom not the occupation, like Maitland states “the work itself is not the vocation”.[2] Vocation calls Christian ministry to reach all aspects of ones life, a way of life many believe. In short, Christian ministry, as a whole, is any vocational work done for the sake of the Great Commission.

Someones ministry is shaped by what they feel called to do. Vocation can be any activity as a whole, or specific activities, or organizations within a church dedicated to specific activities. Some ministries are identified formally as such, and some are not; some ministry is directed towards members of the church, and some towards non-members.

Now, personally, I think that sticking Trump into that category is pretty bonkers too, but what I’m getting at is that she’s not saying that he’s an ordained priest or anything like that.

You misunderstand; its Ministry (the band) /s

Trump isn’t even Christian. That much is obvious.
