During the White House Easter Egg Roll, Melania Trump gently nudged President Trump to place his hand on his heart for the singing of the national anthem.

The Easter Egg Roll at the White House is an event packed with excitement, and, it appears, distractions. 
It’s unclear if President Trump was focused on the crowd filled with gleeful children, a massive lawn packed with games and hidden eggs, or the appearance of the Easter Bunny, but he did seem to lapse on one important gesture. 
During the Monday's event, as the national anthem began to play, he did not put his hand over his heart. 
Thankfully, First Lady Melania Trump was at his side and gave him a reminder in the form of a nudge. 
The president quickly responded and joined the others in the gesture.
