The Magnitsky Act is a US law sanctioning Russia by banning 18 powerful individuals from entering the US.  These individuals were responsible for fraud and corruption and shutting down and imprisoning Sergei Magnitsky, a Russian lawyer and whistle blower who discovered major fraud and corruption involving $ hundreds of millions in the tax department of Russia and in a major Bank (and Putin and mobsters and Oligarchs controlled it). Putin hates this law with a passion and wants it gone. Putin retaliated by passing a law banning US adoptions of Russian children. Putin launched an onslaught of US PR firms and individuals, some Russian Americans to eliminate the sanction and this is what the Russians wanted from Trump's people. Magnitsky died (killed) in prison and his lawyer was thrown out of his apartment window several stories up before a key hearing on the case. The money has disappeared. It is not "just about adoptions".
