Firebrand South African politician Julius Malema was found guilty of violating the nation’s gun laws for firing a weapon at a political rally in 2018.

The East London Magistrate’s Court handed down its verdict at a hearing on Wednesday. Sentencing will take place at a later date, Magistrate Twanet Olivier said.

Malema heads the Economic Freedom Fighters (EFF), which advocates for the expropriation of mines, banks and land, and is notorious for starting brawls in parliament. It won 9.5% of the vote in last year’s election, making it the fourth-biggest party and giving it 39 of the 400 seats in the National Assembly.

Malema will be disqualified from serving in the legislature if he is sentenced to more than 12 months in prison without the option of a fine and fails to have the judgement overturned on appeal.

The case stems from a video that went viral on social media and showed Malema appearing to fire shots into the air with what looked like an automatic rifle at an EFF rally in the town of Mdantsane in the Eastern Cape province in July 2018. He denied wronging, with his lawyer arguing that he had used a toy rifle and blank cartridges, rather than live ammunition — an argument the court rejected.

Malema has been in US President Donald Trump’s crosshairs for singing a song dating back to the apartheid era that calls for White Afrikaner farmers to be killed.

At a meeting with his South African counterpart Cyril Ramaphosa in the White House in May, Trump falsely alleged that the farmers were being subject to a genocide and questioned why no action had been taken against Malema over his inflammatory actions.
