Good point, though lobbying groups are often endorsing and donating to candidates and are backed by sentiment in other regimes like AIPAC. I guess $TRUMP is just creating another backdoor around foreign donation regulations.
In the US, lobbyists representing foreign interests must register as such. Failure to register is a crime: that's what Michael Flynn was convicted of, before Trump pardoned him.
In contrast, any foreign party can purchase $TRUMP.
