Civil rights organizations have filed suit seeking to block any deployment of armed federal officers near polling places this fall, citing a federal law that has long prohibited armed personnel from being stationed at or near voting sites.

The prohibition on armed officers at polling places dates back decades and has generally been understood as a bright-line rule meant to keep the machinery of voting free from the appearance of coercion. Plaintiffs argue that recent statements and planning documents suggest agencies may be considering a more visible posture near voting sites this cycle.

Legal scholars note that courts have historically enforced the polling-place prohibition strictly, given its clear statutory basis and long history of bipartisan support.
