President Joe Biden briefly wore a red Trump campaign hat at an event commemorating the 23rd anniversary of the 9/11 attacks.
He was visiting firefighters in Pennsylvania near where one of the four hijacked planes crashed, and the White House said he donned the cap as a gesture of unity.
Video recording the incident shows the president having a friendly conversation with a Trump supporter before they swap headwear.
Donald Trump's campaign was quick to see the funny side. "Thanks for the support, Joe!" one post read with a photo of Biden in the trademark Republican hat.
