What you are saying is that it is possible to catch the most blatant and frequent inside traders. Insider information does not have to be "frequent" to be profitable "insider information" situation.
Which is specifically unlikely to cover senate people or even most people having access to inside information in this or that special circumstances.
> This sentence kind of suggests to me that you might be thinking of some atypical case of insider trading, perhaps involving politicians rather than corporate insiders?
The OP specified "members of the US Congress" as his group of interest. However, I think that yours "it is atypical to be engaged in insider trading that does not involve high frequency of trades" is just incorrect.
You don't have to be a frequent trader to make a lot of money insider trading, you do have to make very high confidence (i.e. risky) trades though. A single one of those will stand out, not the frequency. Unless you're a habitual options trader or something, such trades will instantly be a huge red flag.

My bad, I missed that. I suspect it's inherently harder to investigate members of congress for anything, but I also suspect that there's far less illegal insider trading happening by members of congress than people often suggest. I'm not sure there's really any very good evidence that congresspeople are beating the market, someone tried to look at the numbers here https://www.maximum-progress.com/p/congressional-insider-tra...
