The U.S. voiced concern about potential foreign interference in Romania's presidential election after the declassification of documents showing the country was a target of "aggressive hybrid Russian attacks" during a period of three consecutive ballots.

Having previously polled in single digits, pro-Russia ultranationalist Calin Georgescu surged to victory in the first presidential election round on Nov. 24, causing widespread surprise in the European Union and NATO member state.

Documents declassified by Romania's top security council on Wednesday showed Georgescu was massively promoted on social media platform TikTok through coordinated accounts, recommendation algorithms and paid promotion. Georgescu has declared zero funds spent in the campaign.
They also showed compromised login data to Romanian election websites and over 85,000 cyber attacks during the election. Romania's intelligence agency said the campaign's size, methods and coordination pointed to a foreign state.
