Well we know the Swimmer seeked help from the Soviets against Reagan.
And then we have the $500 000 to the "bent one" for a speech from the Russian bank.
From the ZH piece:
As for Trump being a secret plant for the KGB, one can make a far more "disturbing" assertion that it is Clinton, not Trump, who is in the Russians' pocket. As the WSJ recalled in late 2015, it was Clinton, not Trump, that was paid $500,000 to make Russian problems go away:
The Russian government was opposed to sanctions. At the time, the Obama administration was attempting to reset relations with Russia. The State Department rebuffed the request from Congress. “We…do not support such a measure at this time,” a department official wrote to one senator.
A few weeks later, Bill Clinton participated in a question-and-answer session at a Renaissance Capital investors conference. He was paid $500,000. After the appearance, Mr. Clinton received a personal thank-you call from Vladimir Putin, then the Russian prime minister, the government news agency TASS reported.
Renaissance Capital is one of Russia's largest investment banks.
