An Arizona House candidate says foreign money is shaping US races, and the claim points at a well-connected Republican operative — bad news for the campaign-finance rules that are supposed to stop it.

• Kai Newkirk, a Democrat running in Arizona's 4th district, filed a foreign election interference complaint with the state attorney general.
• The target is Brad Parscale's firm Clock Tower X, registered as a foreign agent and paid by Israel through a media middleman to run digital campaigns.
• Money reportedly flows on to subcontractors that are not registered as foreign agents, including groups with names like Friends of Peace.
• The campaign was sold publicly as fighting antisemitism online, but a stated aim was keeping young conservatives from turning against Israel.
• Enforcement is thin: the Justice Department task force that policed foreign agent rules was disbanded early in the Trump administration.

Outlook: Whether anything comes of this rests on the Arizona attorney general, since federal enforcement has been gutted.
