I know, I felt the same way about Rush. I have not fully come back to a total trust no matter how glowing he now is about Trump.
Once he got back on the train, it took me a while before thinking he was trustworthy again.
He and his brother have become full throated supporters, and that's important. They're welcome back, and good allies now.
I will always feel a bit betrayed by what he did. Won't forget.
