Donald Trump did not say "It burns when I pee" during his United Nations speech. This claim is false and originated from satirical social media posts that went viral after his speech. There is no evidence or official record supporting this statement. Major news outlets and the official transcript of Trump's nearly one-hour speech confirm that he focused on topics such as national sovereignty, immigration, trade policies, and criticism of the UN's effectiveness without making any such bizarre or personal remarks. The viral story was a clear example of satire mistakenly taken as fact on social media.
