... On June 9, 2025, a photograph of U.S. President Donald Trump spread online, claiming he was wearing a catheter under his suit while at an Ultimate Fighting Championship (UFC) event. The photograph in question showed fighter Kayla Harrison, who had just won the UFC women's bantamweight championship bout, putting her victor's belt around Trump's waist.
A number of posts on X, Facebook, YouTube, and TikTok made this claim. One post stated:

... The following YouTube video compiles a range of clips of Trump walking into the UFC arena and interacting with Harrison. At the 32-second mark, Harrison puts her championship belt over his shoulder. We paused at numerous moments in the clip and found there was a noticeable shadow on Trump's leg but no evidence of a bulge as he stood at that angle. ...
It is possible the bulge was visible when Harrison wrapped the belt around Trump's waist, pulling his pants back. However, there is no way to independently verify whether this bulge is from a catheter.
We also zoomed in on the image in question and found a similar shadow on Trump's other leg, indicating that the bulge is likely also just a result of the angle of the light. ...
