President Donald Trump and first lady Melania Trump were among the Americans to check out the total eclipse on Monday.

The Trumps, along with their son Barron, watched the eclipse from the Truman Balcony at the White House.

Trump briefly stole a glance at the sun sans-protective glasses, something many people, including scientists and former eclipse-watchers who’ve experienced blindness, cautioned against. An aide standing below shouted, “Don’t look,” according to a White House pool report.
