For the record, he is very much anti-Trump and even more so anti-Musk.
I'm on medications which are either dependency forming, expensive, or both. As such, I told him that my family was concerned about what would happen if current government actions cost me my SSI or Medicaid. He did not personally believe they would be cut to that extent, if at all, because it would be absolute chaos. Half of his patients would have no way to continue their treatment. I told him that was my thinking exactly, which is why I was talking to him now about withdrawal.
Again, because he has some hope that cutting these programs would be a step too far (hitting MAGA as much as everyone else), we agreed not to withdraw for now. However, if anything should happen, he's promised me a weaning plan and replacement with the best non-habit forming medications he can arrange.
I'd like to be as lighthearted as others about why Hawley is raising this issue, but as a physically disabled person who only has this much bodily sanity because of SSI and Medicaid, I can't manage a laugh here. It's really dire, serious stuff for a lot of people.
