There is a viral, false claim circulating on social media that President Donald Trump said "It burns when I pee" during his speech at the United Nations General Assembly in September 2025. This claim is satirical and not true; there is no evidence that he actually said this phrase during the speech. The original satirical post appeared on social media and sparked widespread attention and the hashtag #BurnsWhenIPee trending worldwide, but it was confirmed to be fake news.

Regarding the phrase "it burns when I pee," medically this describes painful urination, which could be caused by multiple conditions such as a urinary tract infection (UTI), sexually transmitted infections (STIs), bladder or urethral inflammation, or vaginal infections. This symptom warrants medical evaluation for proper diagnosis and treatment.

In summary, the statement attributed to President Trump is false and originates from satire, while the sensation of burning during urination is a common symptom associated with various treatable medical conditions.
