After 2016, Republicans appointed a Republican Special Councilor who determined as fact that Russia "interfered in the 2016 presidential election in sweeping and systematic fashion" to help Trump / hurt Clinton.
After that, the Republicans formed the Senate intelligence committee on the Russia investigation which came to the same conclusion.
Cambridge Analytica didn't come out till a couple years later I think, but that's all been proven as well.
Also, AIPAC is an American organization. There aren't any laws against Americans lobbying their own government over foreign policy matters, so I don't think anything will come of this. I'm not that confident though.
Maybe Russia can find an American citizen, any American citizen, wire him a billion dollars, and he would then be legally allowed to buy out any politician based on your standards.
Why not have Iran, Afghanistan and North Korea join in the party as well?
And while we're at it, AIPAC is legally allowed to receive donations from foreign nationals given it's legal status as a Social Welfare Organization. And they don't even have to disclose it.

But imagine what would happen if someone in American tried to start an organization for any of the afformentioned countries. Similarly, the Muslim Brotherhood faces sanctions as if it were a terrorist group. Albeit in the US it functioned like nothing more than a mere lobby by Americans. Similarly with Russia's RT being labeled a Russian adversary.
Israeli Jews in the US are allowed to buy politicians and run the media without any interference however.
If America didn't have double standards, AIPAC would have been sanctioned for being supported by a designated terrorist genocidal state as per international law and a few media empires owned by media moghuls with well documented ties to the Zionist lobby would have been broken up too.
But if a foreign adversary can buy an election with at least $200 million and none of the major politicians bat an eye, maybe the US political establishment has gone too far to look back now. Maybe time for a change.
