"Voices are being heard, there is a thread of truth coming from the almost iron curtain of authoritarianism we have reverted to in Russia," said Wicker from the Senate floor.

The bill would ensure that the 60 or so officials allegedly involved in the crime will not be able to receive travel visas to the United States.

The bill, according to Cardin's website, would "seek to combat what has become a toxic atmosphere of impunity in Russia where despite occasional rhetoric from the Kremlin, the authorities have failed to follow through with meaningful action to stem rampant corruption or bring the perpetrators of numerous and high-profile crimes to justice."

Both Wicker and Cardin outlined the sordid tale of Magnitsky's death in prison after he discovered and publicized one of the greatest tax fraud schemes in modern history.

"In an Orwellian turn of events … those involved in his murder are moving to try him for the very tax crimes they committed," said Cardin. "Think of the irony here. He exposed corruption in Russia. As a result he was arrested imprisoned, tortured and killed."
