Over 120.000 people protested in Bucharest alone and some other 200.000 in the rest of the country

Over 300.000 people took the streets all over the country, as one of the beneficiary of the already famous government's decrees would be the President of the Socialist Party (PSD) of Romania himself - Liviu Dragnea. Protesters accuse PSD of creating a law especially designed to save their president, which is currently prosecuted for corruption, from going to prison.

The US embassy in Bucharest, the EU Commission and many EU officials have blamed this action and pointed out that it's a huge step backwards for the democracy and rulse of law in Romania. Even more, the European Commission vice-president, Frans Timmermans, urged the government to “urgently reconsider”, saying that Romania’s EU funding could be at risk.

In a separate statement, the US, Germany, Canada, Finland, the Netherlands and France said the government had undermined “progress on rule of law and the fight against corruption over the past 10 years”.
