The "official" line is that he mentioned personal information about the ICE officer who killed Renee Good in his criticism, which they are forcefully misconstruing as doxxing/incitement to harass. Which all completely falls apart when you consider the information was already reported on by major news outlets and completely public/part-and-parcel of tens of thousands of similar posts. But our government is made of shameless knuckle-draggers, so here we are.
