The Obama administration issued an executive order Thursday authorizing sanctions on individuals and organizations it believes were involved in alleged Russian interference in the 2016 U.S. election.

The White House sanctioned nine entities and individuals: two Russian intelligence agencies, four officers of its largest intelligence agency, GRU, and three companies that supported GRU's operations. The White House also expelled 35 Russian diplomats and closed two Russian compounds in New York and Maryland in response to what it said was harassment of American diplomats in Moscow.
