Thousands of Trump supporters have gathered in several cities along the Mexican border over the last two days, to start building a border wall between Mexico and the United States.
More than 3000 volunteers showed up near San Diego in California and 2000 near Yuma in Arizona, many of them showing up with tools, machinery and even materials.
The movement seems particularly popular in Texas, where 3000 people gathered near Laredo, 5000 in San Antonio, 2000 in Brownsville as well as almost 8000 workers spread across other locations along the border.
Many of the workers are actually construction professionals who have decided to volunteer and give some of their time for the cause.
Some business people like the San Antonio based engineer and owner Harris-TEXCON, David Harris, have decided to invest some large amounts of their own money to fund the border wall.
