CNN promotes Donie O'Sullivan to senior correspondent

Irish journalist Donie O’Sullivan has been promoted to CNN Senior Correspondent.

O'Sullivan first rose to prominence after reporting on January 2021's far-right Capitol Hill riots.

The Kerryman's reporting focuses on the spread of online misinformation, and now specialises in highlighting the effect of conspiracy theories, extremism, and radicalisation on politics, culture, and society.

In 2024 the journalist received Emmy nomination for “outstanding science and technology coverage” for his in-depth reporting on the effect social media platforms and conspiracy theories have on American families.

O’Sullivan will continue his reporting across all CNN platforms on the role misinformation is playing in the 2024 election, including new episodes of MisinfoNation in-depth specials on the subject, as part of The Whole Story with Anderson Cooper, that will air this autumn.

He first joined the network in 2016 as a producer. He went on to become a technology reporter with CNN Business, and over the years he has worked closely with CNN’s investigative unit.

Sharing the news on X, the journalist said: "The Rollercoaster continues. Busy year ahead!".

Notably, the CNN correspondent was part of the reporting team that uncovered several major Russian government-linked social media campaigns targeting Americans in the run-up to the 2016 US presidential election. His work was later used by Congress investigators and others examining the extent of Russian meddling ahead of the election.
