U.S. First Lady Melania Trump had to nudge President Donald Trump during the White House Easter Egg Roll day Monday, reminding her husband to place his hand over his heart during the national anthem.

Videos of Melania Trump poking the president went viral, during which the first lady noticed that Donald Trump forgot to raise his hand to his chest after the Easter Bunny and a singer from the US Marine Corps Band standing next to the couple started singing the anthem.

The videos show the first lady taking action by delivering a light bump with her free hand to the president, five seconds into the U.S. National Anthem.

U.S. President Donald Trump and his wife Melania hosted the annual White House Easter Egg Roll for the first time.

The new president, who took office January 20, thanked the first lady for her efforts in organizing the children's event.
