Australian One Nation senator Malcolm Roberts threatened to report a journalist to the police for “stalking” after he received “persistent” requests for inquiry about his citizenship. Roberts, whose Australian citizenship only became official months after the elections, was reportedly pressed for comments despite rejecting the reporter’s inquiries.

According to ABC, Roberts has been continously pestered by a Fairfax journalist and they have emailed the reporter to halt their actions. “Your persistent emails, despite requests to stop, is classified by our office as stalking,” said Sean Black, the spokesman of Robert’s. “Any continued pestering or harassment from you or your colleagues or anyone, including me, from our office of organization will be referred to the Queensland police.”

The Fairfax journalist mainly asked questions regarding Robert’s interview with Sky News yesterday. In the interview, Roberts said he told British authorities back in December 5 that he was not a British citizen. Roberts also sent emails to British authorities two months before the elections, reports The Australian.

“(I) said I believe I am not a British citizen, and just in case though if I am I renounce it effective immediately,” Roberts said. “I’d taken all steps that I’d reasonably believed necessary.”

The constitution of Australia notes that citizens of another country cannot nominate or sit in parliament, reports The Australian. In previous cases where a candidate cannot renounce their citizenship or allegiance to another country, the High Court ruled that one must perform all “reasonable steps.”

Meanwhile, in a separate report from ABC, Fairfax quoted Sean Black regarding his statement on Robert’s citizenship: “He is preferring to believe that he was never British because he has no allegiance or exercised any citizenship arrangement,” Black said as quoted by Fairfax. “There is nothing wrong or incongruent with Malcolm Roberts putting his hand up and saying, ‘as far as I’m concerned I’m not British, never was’ – the British Government may have a different view.”
