The Magnitsky Act ostensibly seeks to punish Russians who are alleged to be complicit in the untimely death of Russian citizen Sergey Magnitsky, a lawyer. It has been widely reported that the Obama administration believes the Congressional initiative is unnecessary. Dunkerley's analysis suggests that Congress members were duped into supporting an anti-Russia initiative of foreign agitators.
According to Dunkerley this isn't the first time Congress has become involved in a foreign-based campaign against Russia. He reports that in 2007 Congresswoman Ileana Ros-Lehtinen introduced legislation accusing the Russian government of murdering reputed former KGB spy Alexander Litvinenko in London. Dunkerley's book, The Phony Litvinenko Murder, documents that the entire story about Litvinenko was a media fabrication, inspired by a wealthy arch-enemy of Russian president Vladimir Putin.
