I'm not aware of this being a widespread practice at anti-Trump rallies.

> Do they need to subpoena ~400 lawmakers and $10 donors to the campaign? I think it’s obvious that that is overreach and intimidation.

Well... it's not unlikely that there might have been "inside help" from lawmakers and/or their staff or even general Congressional staff. The purpose of an investigation is to go, dig deep and fully take apart whatever conspiracy there was.

As for the donors - anti-terrorist laws in pretty much every country don't care if it was just a $10 donation. Donate to a cause that ends up being terrorists, be labeled as a terrorism supporter.

the gallows mockup was one of the reasons for the reaction to the Jan 6th stuff.[0] , although as far as what political party the owning group is using it for or against is sort of up for grabs.
