During a rare joint appearance at a Washington, D.C. military parade on June 14—celebrating both the U.S. Army’s 250th anniversary and Donald Trump’s 79th birthday—an intimate moment between the former president and First Lady Melania Trump caught viewers’ attention.

As the couple stood side by side amid formal fanfare, Melania gently touched Trump’s back, and he responded with a soft pat. According to lip reader Jeremy Freeman, Trump whispered, “Thank you, baby.” Fans saw it as a sweet display of affection.
