On the night of May 28, a few hours after the Italian president refused to appoint Eurosceptic Paolo Savona the country's new finance minister, a massive attack was launched against the first in social networks. In particular, anomalous activity was spotted on Twitter, where within just several minutes, more than 400 anti-Matarelli accounts were created.

As ANSA notes, traces of all profiles led to a single source - the Russian "troll factory."

Tweets targeting the president, often vulgar, called on his resignation.
