Miller said that Russia has yet again chosen “confrontation and escalation over constructive diplomatic engagement.” He further said that the US would “respond appropriately” to Russia’s actions. While addressing a press briefing on Thursday, Matt Miller said, “This unprovoked expulsion of our diplomatic personnel is wholly without merit, as is the case against a former Russian contractor of our embassy who was arrested for the supposedly nefarious task of performing such activities as providing our embassy with media clips.” He further said, “Yet again, Russia has chosen confrontation and escalation over constructive diplomatic engagement. It continues to harass employees of our embassy, just as it continues to intimidate its own citizens. We regret that Russia has taken this path, and you can certainly expect that we will respond appropriately to their actions.” Miller said the expelled US diplomats have not yet left Russia, according to CNN. The expulsion of the two US diplomats comes at a time when the ties between Washington and Moscow have been strained. In a statement, the Russian Foreign Ministry said that Tracy was given “a harsh demarche with the presentation of an official note regarding the incompatibility with the diplomatic status of the actions of the First Secretary of the US Embassy Jeffrey Sillin and the Second Secretary of the Embassy David Bernstein.”
