It’s Flag Day, a day that honors the adoption of the United States flag on June 14, 1777. The original resolution declared the flag would have 13 alternating red and white stripes and a blue field with 13 white stars, representing a new constellation — a powerful symbol of unity and independence that continues to fly proudly today.

As the protests continue, Mexico's flag has made several appearances. However, the waving of this flag expands beyond support for immigrants in the country.

Former Foreign Minister of Mexico Jorge Castañeda, who is currently a global distinguished professor of politics and Latin American and Caribbean studies at New York University, joins CNN’s Polo Sandoval to share his take on protesters waving the Mexican flag at the anti-ICE protests in Los Angeles.
