Here is a concise description of the scene: The video shows a large crowd of people gathered on a street and steps in front of a large, white building with arched entrances and columns. Many people are carrying signs and flags, including American and Mexican flags. Some signs show anti-Trump sentiments. The crowd appears to be part of a protest or demonstration, with people walking and standing in a somewhat organized manner. The camera pans upwards to show the scale of the crowd and the building they're gathered in front of. There are cars visible in the street near the crowd. The day appears to be bright and sunny.
