Indeed, the Trump administration rolled-back an Obama era rule that financial advisors must be fiduciaries. I'm not sure most people realized that happened.
Sorry if that came off as political, I mentioned the leadership at the time as epoch markers as I didn't recall off-hand the specific dates. I suspect people didn't realize that the fiduciary rule wasn't a thing prior to 2015, let alone that it was over by 2018, and it is my understanding the Trump administration was looking at resurrecting the rule.
