Ukrainian President Volodymyr Zelensky signed into law a controversial statute expanding the government’s power to regulate media groups and journalists in the country.

Zelensky signed the legislation on Thursday over the objections of media unions and press freedom organizations, who warned it will have a chilling effect on free speech.

Under the new law, the National Television and Radio Broadcasting Council, whose members are appointed by the president’s administration and by members of parliament, will have broader authority over Ukrainian media organizations and journalists.

The regulatory agency can effectively shut down news sites that aren’t registered, according to the Kyiv Independent.
