California Governor Gavin Newsom's press office labelled President Donald Trump "Dozy Don" after he appeared to close his eyes during an event.
The incident occurred at the first meeting of the Board of Peace in Washington, D.C., where Trump announced pledges for a Gaza reconstruction fund.
Social media users, including former Republican congressman Adam Kinzinger and The Lincoln Project, also commented on Trump's appearance, suggesting he was tired or asleep.
White House spokesperson Anna Kelly defended Trump, stating he is the "sharpest, most accessible, and energetic president in American history" and criticised The Independent.
Newsom, a potential 2028 Democratic presidential nominee, has previously used social media to criticise Trump, often mimicking his all-caps posting style.
