Russia–United States relations
The United States and Russia begin fighting over the extradition of Yevgeniy Nikulin, who was detained in October 2016 in the Czech Republic, after the U.S. Justice Department issued an international arrest warrant for him. However, soon after the U.S. issued its arrest warrant, Russian authorities also sought his extradition. The Russian charge accuses Nikulin of stealing from an online money transfer company back in 2009.
