Russia is considering retaliation against sanctions imposed by former President Barack Obama, possibly including expelling 30 U.S. diplomats and seizing two U.S.-owned properties in Russia.
Obama expelled 35 Russian diplomats and seized two Russian-owned properties in December in response to leaders of the CIA, FBI, and NSA accusing Russia of hacking a server of the Democratic National Committee (DNC) and leaking incriminating emails. The agencies never provided substantial proof and were prevented by the DNC from accessing the server.
