That’s true about the staff of some agencies that support Congress, but presumably because of their greater number (and influence?), “Congressional staffer” in a U.S. context usually refers to partisan staff, at least as I’ve heard it used. (There’s ~5x [edit: actually, 3x is more accurate—the earlier estimate mistakenly included partisan staff who are non-DC-based] more partisan advisors and assistants than nonpartisan research staff, and I’d be surprised if the latter did negotiation or led work on some piece of legislation. I compare “advisors and assistants” to “research staff” because nonpartisan non-research staff work at places like the Government Printing Office, which I’d guess aren’t very influential.)

In this case, it’s basically like in the EP.
