“I hope the president will make this decision voluntarily and he has not removed this issue of state sponsors of terrorism from the agenda,” Blumenthal said on CNN.

Graham stressed that Congress is ready to take the appropriate decision.

Earlier, the official representative of the Russian Foreign Ministry, Maria Zakharova, admitted the severance of diplomatic relations with the United States if US lawmakers decide to declare Russia a "country sponsor of terrorism."

In July, the US Senate passed a resolution calling on the State Department to recognize Russia as a state sponsor of terrorism due to events in Chechnya, Georgia, Syria and Ukraine.

Press Secretary of the Russian President Dmitry Peskov said that the Kremlin negatively assesses the consequences for relations with the United States if Russia is recognized as a country sponsoring terrorism.
