Magnitsky Act provides sanctions against Russians involved, according to the congressmen, in human rights violations.
The Treasury has not yet provided an explanatory note to the expanded list posted on its website.
The Magnitsky Act, which was signed by US President Barack Obama in December 2012, introduces visa and financial sanctions on individuals deemed by Washington to be complicit in the 2009 death of whistleblowing Russian lawyer Sergei Magnitsky in a Moscow jail, as well as other purported human rights abuses.
Russia has in the past responded to such targeted sanctions in a proportional manner.
Previously, it issued its own blacklist of 18 US officials described by Moscow as having been connected with the US’s infamous Guantanamo Bay detention camp in Cuba or as having violated the rights of Russians abroad.
