Findings
| When | Description | Source |
|---|---|---|
| 2021 | O'Donnell was found in contempt of court after uploading Destiny game assets to YouTube and Bandcamp, despite a court order prohibiting him from sharing them. The court imposed sanctions, including requiring him to remove the material and pay related legal costs. | Source |
| 2026 | He has repeatedly supported Trump, voted for him and campaigned as a Republican. Trump endorsed his 2026 congressional campaign, and O'Donnell publicly expressed gratitude and pledged to work with him. | Source |
| 2024 | He has stated that he opposes abortion, although he favours leaving the issue to individual states rather than imposing a national ban. | Source |
| 2025 | He has criticised diversity, equity and inclusion initiatives in the video-game industry, including offering gender-neutral character options and pronoun selection. | Source |
| 2026 | O'Donnell controls The Marty Army, an online community originally established as a Halo fan forum. An October 2026 Associated Press investigation found racial slurs, Nazi praise, Holocaust minimisation and white-nationalist conspiracy theories among thousands of posts. Although O'Donnell has condemned bigotry and his campaign says nearly 200 users were banned, substantial hateful content remained accessible. | Source |
| 2026 | O'Donnell publicly endorsed the Trump administration's military campaign against Iran, describing it as a necessary confrontation with the Iranian regime and praising Trump for fighting what he called "Islamo-fascists." He specifically cited preventing Iran from obtaining nuclear weapons as a justification. | Source |
| O'Donnell has repeatedly expressed opposition to LGBTQ+ equality, including same-sex marriage and gender-affirming care. He has described LGBTQ+ people as part of an existential threat to Western civilisation, condemned Pride as sinful, and endorsed rhetoric portraying LGBTQ+ people as a threat to children. | Source |
