The lawsuit was brought in opposition to the council's handling of a petition about the 'bathroom bill'. The pastors have been called to provide evidence because the defence alledges that they were involved in organising the petition. Maybe they weren't involved in it. Or maybe they were but they have nothing to say/provide that's germaine to the case. Or maybe they do but those sermons are not it. Whatever the truth, the lawyers are alledging that the pastors were involved in carrying out the petition and that such is relevant to the case.
The tweet states that they have entered the political area and there for are "fair game".
She is attacking them politically because they have become political.
That is what the tweet says.
I still think they should be freely giving any preaching to whoever will read it.
