If they’ve been fine with Congress trading stocks on insider knowledge forever why would this be any different?

This is actually a good example of this not being a partisan issue. A congressional stock trading ban is one of the few issues that doesn't break down by party lines. Both Republicans and Democrats have put forward bills to ban it and the percentage of the population in support of such efforts is very similar between Republicans and Democrats.

I'm also not going to defend Congressional stock trading. I think it should be banned. But there are some differences about who is doing the trading/betting, what specifically they are trading/betting on, and what that information communicates to the public. There's a fundamental difference between a random staffer betting the US will attack Iran on a certain date which becomes public immediately compared to a Congressperson themselves buying stock in a weapon manufacturer in the leadup to an attack knowing the purchase won't be disclosed to the public for up to 45 days.

Like I said, I would be against both, but it's much easier to justify Congressional stock trading than the insider trading we see on these prediction markets. Afterall, it isn't like Congress is moving to remove all insider trading legislation, so there is some recognition of nuance here even if they give themselves more leeway than we would want.

Because the law protects members of Congress, not

>people close to the administration.
